   The impact of ATLAS and CMS single differential top-quark pair measurements at $\sqrt{s}=8$ TeV to CTEQ-TEA PDFs

   Musajan Kadir🇨🇳 · Alim Ablet🇨🇳 · Sayipjamal Dulat🇨🇳 · Tie-Jiun Hou🇨🇳 · Ibrahim Sitiwaldi🇨🇳

   By applying the Error PDF Updating Method, we analyze the impact of the absolute and normalized single differential cross-sections for top-quark pair production data from the ATLAS and CMS experiments at the Large Hadron Collider, at a centre-of-mass energy of $\sqrt{s}=8$ TeV, on the CT14HERA2 PDFs. We find that the top quark pair single differential distributions provide minor constraints on the CT14HERA2 gluon PDF when the nominal CT14HERA2 inclusive jet production data are included in the fit. Larger constraints on the gluon distribution are present when the jet data are removed (CT14HERA2mJ) and/or when increased weights are given to the top data in the CT14HERA2 fits. The weighted $t\bar{t}$ data provide significant constraints on the CT14HERA2mJ gluon PDF, that are comparable to those obtained from inclusive jet production data. Furthermore, we examine the top quark mass sensitivity of the top-quark pair single differential distributions.

   Simple Hidden Sector Dark Matter

   Patrick Barnes🇺🇸 · Zachary Johnson🇺🇸 · Aaron Pierce🇺🇸 · Bibhushan Shakya🇨🇭

   A hidden sector that kinetically mixes with the Minimal Supersymmetric Standard Model provides simple and well-motivated dark matter candidates that possess many of the properties of a traditional weakly interacting massive particle (WIMP). These supersymmetric constructions can also provide a natural explanation for why the dark matter is at the weak scale - even if it resides in a hidden sector. In the hidden sector, a natural pattern of symmetry breaking generally makes particles and their superpartners lie around the same mass scale, opening novel possibilities for a variety of cosmological histories and complex indirect detection signatures.

   Core meets corona: a two-component source to explain Lambda and anti-Lambda global polarization in semi-central heavy-ion collisions

   Alejandro Ayala🇲🇽 · Marco Alberto Ayala Torres🇲🇽 · Eleazar Cuautle🇲🇽 · Isabel Dominguez🇲🇽 · Marcos Aurelio Fontaine Sanchez🇲🇽 · Ivonne Maldonado🇲🇽 · E. Moreno-Barbosa🇲🇽 · P. A. Nieto-Marin🇲🇽 · M. Rodriguez-Cahuantzi🇲🇽 · Jordi Salinas🇲🇽 · Maria Elena Tejeda-Yeomans🇲🇽 · L. Valenzuela-Cazares🇲🇽

   We compute the Lambda and anti-Lambda global polarization in semi-central heavy-ion collisions modeling the source as consisting of a high-density core and a less dense corona. We show that when more Lambdas than anti-Lambdas are produced in the corona, and this is combined with a smaller number of Lambdas coming from the core, as compared to those coming from the corona, an amplification effect for the anti-Lambda with respect to that of Lambda polarization can occur. This amplification becomes more important for lower collision energies and quantitatively accounts for the Lambda and anti-Lambda polarizations measured by the STAR beam energy scan.

   Production mechanisms of open-heavy flavor mesons

   Ivan Schmidt🇨🇱 · Marat Siddikov🇨🇱

   In this paper we discuss different mechanisms of open-heavy flavor meson production. Using the color dipole framework, we analyze in detail the contributions of the conventional two-pomeron fusion and the three-pomeron fusion correction. In a parameter-free way we found that the three-pomeron mechanism is significant for $D$-meson production in the small-$p_T$ kinematics, although it is less important at large $p_T$, as well as for $B$-mesons. The inclusion of the three-pomeron mechanism significantly improves the agreement of theoretical predictions with experimental data in the small-$p_T$ kinematics. We also consider the non-prompt charmonia production, and demonstrate that the theoretical results are in reasonable agreement with experimental data. Finally, we compare the theoretical predictions for the dependence on multiplicity of co-produced hadrons to experimental data recently measured by the ALICE collaboration. We found that, contrary to naive expectations, the contribution of the three-pomeron mechanism has only a mild effect on the self-normalized observables in the range of multiplicities studied at ALICE, and for this reason the two-pomeron fusion mechanism can describe reasonably well the experimentally observed multiplicity dependence.

   Investigating the diffractive gluon jet production in lepton-ion collisions

   G. M. Peccini🇧🇷 · L. S. Moriggi🇧🇷 · M.V.T. Machado🇧🇷

   We study the diffractive jet production in electron-ion collisions in the kinematical region where the mass $M_X$ of the diffractive final state is larger than $Q^2$. Based on parton saturation framework predictions are done for the kinematics of future or possible $eA$ machines as the EIC, LHeC, HE-LHeC and FCC-eA. We analyze the differential cross section as a function of jet (gluon) transverse momentum and from the experimental point of view this observable could be used to extract the saturation scale as a function of $x_{IP}$.

   Connecting fluctuation measurements in heavy-ion collisions with the grand-canonical susceptibilities

   Volodymyr Vovchenko🇩🇪 · Oleh Savchuk🇺🇦 · Roman V. Poberezhnyuk🇺🇦 · Mark I. Gorenstein🇺🇦 · Volker Koch🇺🇸

   We derive the relation between cumulants of a conserved charge measured in a subvolume of a thermal system and the corresponding grand-canonical susceptibilities, taking into account exact global conservation of that charge. The derivation is presented for an arbitrary equation of state, with the assumption that the subvolume is sufficiently large to be close to the thermodynamic limit. Our framework -- the subensemble acceptance method (SAM) -- quantifies the effect of global conservation laws and is an important step toward a direct comparison between cumulants of conserved charges measured in central heavy ion collisions and theoretical calculations of grand-canonical susceptibilities, such as lattice QCD. As an example, we apply our formalism to net-baryon fluctuations at vanishing baryon chemical potentials as encountered in collisions at the LHC and RHIC.

   On the Singular Behavior of the Chirality-Odd Twist-3 Parton Distribution e(x)

   J.P. Ma🇨🇳 · G.P. Zhang🇨🇳

   The first moment the chirality-odd twist-3 parton distribution $e(x)$ is related to the pion-nucleon $\sigma$-term which is important for phenomenology. However, the possible existence of a singular contribution proportional to $\delta (x)$ in the distribution prevents from the determination of the $\sigma$-term with $e(x)$ from experiment. There are two approaches to show the existence. The first one is based on an operator identity. The second one is based on a perturbative calculation of a single quark state with finite quark mass. We show that all contributions proportional to $\delta (x)$ in the first approach are in fact cancelled. To the second approach we find that $e(x)$ of a multi-parton state with a massless quark has no contribution with $\delta (x)$. Considering that a proton is essentially a multi-parton state, the effect of the contribution with $\delta (x)$ is expected to be suppressed by light quark masses with arguments from perturbation theory. A detailed discussion about the difference between cut- and uncut diagrams of $e(x)$ is provided.

   Magnetic mass effect on the sphaleron energy

   Koichi Funakubo🇯🇵 · Eibun Senaha🇻🇳

   We elucidate a magnetic mass effect on a sphaleron energy that is crucial for baryon number preservation needed for successful electroweak baryogenesis. It is found that the sphaleron energy increases in response to the magnetic mass. As an application, we study the sphaleron energy and electroweak phase transition with the magnetic mass in a two-Higgs-doublet model. Although the magnetic mass can screen the gauge boson loops, it relaxes a baryon number preservation criterion more effectively, broadening the baryogenesis-possible region. Our findings would be universal in any new physics models as long as the gauge sector is common to the standard model.

   Revisiting the Bottom Quark Forward-Backward Asymmetry $A_{\mathrm{FB}}$ in Electron-Positron Collisions

   Sheng-Quan Wang🇨🇳 · Rui-Qing Meng🇨🇳 · Xing-Gang Wu🇨🇳 · Long Chen🇩🇪 · Jian-Ming Shen🇨🇳

   The bottom quark forward-backward asymmetry $A_{\mathrm{FB}}$ is a key observable in electron-positron collisions at the $Z^0$ peak. In this paper, we employ the Principle of Maximum Conformality (PMC) to fix the ${\alpha }_s$-running behavior of the next-to-next-to-leading order QCD corrections to $A_{\mathrm{FB}}$. The resulting PMC scale for this $A_{\mathrm{FB}}$ is an order of magnitude smaller than the conventional choice ${\mu }_r=M_Z$. This scale has the physically reasonable behavior and reflects the virtuality of its QCD dynamics, which is independent to the choice of renormalization scale. Our analyses show that the effective momentum flow for the bottom quark forward-backward asymmetry should be ${\mu }_r\ll M_Z$ other than the conventionally suggested ${\mu }_r=M_Z$. Moreover, the convergence of perturbative QCD series for $A_{\mathrm{FB}}$ is greatly improved using the PMC. Our prediction for the bare bottom quark forward-backward asymmetry is refined to be $A_{\mathrm{FB}}^{0,b}=0.1004\pm 0.0016$, which diminishes the well known tension between the experimental determination for this (pseudo) observable and the respective Standard Model fit to $2.1\sigma$.

    Topological term, QCD anomaly, and the eta' chiral soliton lattice in rotating baryonic matter

    Kentaro Nishimura🇯🇵 · Naoki Yamamoto🇯🇵

    We study the ground states of low-density hadronic matter and high-density color-flavor locked color superconducting phase in three-flavor QCD at finite baryon chemical potential under rotation. We find that, in both cases under sufficiently fast rotation, the combination of the rotation-induced topological term for the eta' meson and the QCD anomaly leads to an inhomogeneous condensate of the eta' meson, known as the chiral soliton lattice (CSL). We find that, when baryon chemical potential is much larger than isospin chemical potential, the critical angular velocity for the realization of the eta' CSL is much smaller than that for the pi_0 CSL found previously. We also argue that the eta' CSL states in flavor-symmetric QCD at low density and high density should be continuously connected, extending the quark-hadron continuity conjecture in the presence of the rotation.

    Inflaton as the Affleck-Dine Baryogenesis Field in Hilltop Supernatural Inflation

    Chia-Min Lin🇹🇼 · Kazunori Kohri🇯🇵

    In this paper, we investigate the parameter space in the framework of hilltop supernatural inflation in which the inflaton field can play the role of Affleck-Dine field to produce successful baryogenesis. The suitable value of reheating temperature could coincide with the reheating temperature required to produce lightest supersymmetric particle dark matter. The baryon isocurvature perturbation is shown to be negligible. We consider $p=3$, $p=4$, and $p=6$ type III hilltop inflation and discuss how to connect the models to supersymmetric theories.

    Forward-backward asymmetry in $e^{+}{e}^{-}$ annihilation into pions or kaons revisited

    A.B. Arbuzov🇷🇺 · T.V. Kopylova🇷🇺 · G.A. Seilkhanova🇷🇺

    Forward-backward (charge) asymmetry in the processes of $e^{+}{e}^{-}$ annihilation into a pair of charged pseudoscalar mesons is recalculated in the one-loop approximation. The exact dependence on the meson masses is taken into account. Results known in the literature are partially corrected. The bulk of the charge asymmetry appears due to double-photon exchange in $s$ channel. Experimental studies of the asymmetry can be used to verify the point-like approximation used in calculation of radiative corrections due to emission of photons by pions or kaons.

    The $O({\alpha }^2)$ Initial State QED Corrections to $e^{+}{e}^{-}\to {\gamma }^{\ast }/Z_0^{\ast }$

    J. Blümlein🇩🇪 · A. De Freitas🇩🇪 · C. Raab🇦🇹 · K. Schönwald🇩🇪

    We calculate the complete $O({\alpha }^2)$ initial state radiation corrections to $e^{+}{e}^{-}$ annihilation into a neutral vector boson in a direct analytic computation without any approximation. The corrections are represented in terms of iterated incomplete (elliptic) integrals over alphabets of square--root valued letters. Performing the limit $s\gg m_e^2$, we find discrepancies with the earlier results of Ref.~\cite{Berends:1987ab} and confirm results obtained in Ref.~\cite{Blumlein:2011mi} where the effective method of massive operator matrix elements has been used, which works for all but the power corrections in $m_e^2/s$. In this way, we also confirm the validity of the factorization of massive partons in the Drell--Yan process. We add non--logarithmic terms at $O({\alpha }^2)$ which have not been considered in previous calculations. The final results in the limit $s\gg m_e^2$ can be given in terms of Nielsen integrals.

    Effects of top-quark decay modeling in $t\bar{t}\gamma$ production at the LHC

    Giuseppe Bevilacqua🇭🇺

    We present a systematic comparison of different approaches for the modeling of $t\bar{t}\gamma$ final states with leptonic decays at the LHC. On the one hand, we consider a complete calculation at NLO QCD accuracy which includes all resonant and non-resonant diagrams. On the other hand, we consider predictions in the narrow-width approximation with top quark decays modeled at various accuracies. In this way we quantify the impact of the off-shell effects in $t\bar{t}\gamma$ production. We also discuss the relative importance of double-, single- and non-resonant contributions in the complete calculation. Finally we investigate the fraction of isolated photons from decays of top quarks, which represent a background for measurements of anomalous $t\gamma$ couplings.

    From transition electromagnetic form factors ${\gamma }^{\ast }{\gamma }^{\ast }{\eta }_c(1S,2S)$ to the production of ${\eta }_c(1S,2S)$ at the LHC

    Antoni Szczurek🇵🇱

    We review our recent results for production of ${\eta }_c(1S)$ and ${\eta }_c(2S)$ in the ${\gamma }^{\ast }{\gamma }^{\ast }\to {\eta }_c(1S,2S)$ fusion and in proton-proton collisions via gluon-gluon fusion. The quarkonium wave functions are calculated by solving Schrödinger equation for different $c\bar{c}$ potentials. Using Terentev prescription the light-cone wave functions are obtained. The light-cone wave functions are used then to calculate ${\gamma }^{\ast }{\gamma }^{\ast }\to {\eta }_c$ transition form factors. The theoretical results are compared to the Belle experimental data for ${\eta }_c(1S)$. In addition we discuss our results for two-photon decay width. We present also results of our calculations for proton-proton collisions obtained within $k_T$-factorization approach for different unintegrated gluon distributions. The results for hadroproduction of ${\eta }_c(1S)$ are compared to the LHCb experimental data.

    Testing Lepton Flavor Models at ESSnuSB

    Mattias Blennow🇸🇪 · Monojit Ghosh🇸🇪 · Tommy Ohlsson🇸🇪 · Arsenii Titov🇮🇹

    We review and investigate lepton flavor models, stemming from discrete non-Abelian flavor symmetries, described by one or two free model parameters. First, we confront eleven one- and seven two-parameter models with current results on leptonic mixing angles from global fits to neutrino oscillation data. We find that five of the one- and five of the two-parameter models survive the confrontation test at $3\sigma$. Second, we investigate how these ten one- and two-parameter lepton flavor models may be discriminated at the proposed ESSnuSB experiment in Sweden. We show that the three one-parameter models that predict $\sin {\delta }_{\mathrm{CP}}=0$ can be distinguished from those two that predict $|\sin {\delta }_{\mathrm{CP}}|=1$ by at least $7\sigma$. Finally, we find that three of the five one-parameter models can be excluded by at least $5\sigma$ and two of the one-parameter as well as at most two of the five two-parameter models can be excluded by at least $3\sigma$ with ESSnuSB if the true values of the leptonic mixing parameters remain close to the present best-fit values.

    Deciphering the nature of X(3872) in heavy ion collisions

    Hui Zhang🇨🇳 · Jinfeng Liao🇺🇸 · Enke Wang🇨🇳 · Qian Wang🇨🇳 · Hongxi Xing🇨🇳

    Exploring the nature of exotic multiquark candidates such as the $X(3872)$ plays a pivotal role in understanding quantum chromodynamics (QCD). Despite significant efforts, consensus on their internal structures is still lacking. As a prime example, it remains a pressing open question to decipher the $X(3872)$ state between two popular exotic configurations: a loose hadronic molecule or a compact tetraquark. We demonstrate a novel approach to help address this problem by studying the $X(3872)$ production in heavy ion collisions, where a hot fireball with ample light as well as charm (anti-)quarks is available for producing the exotics. Adopting a multiphase transport model (AMPT) for describing such collisions and implementing appropriate production mechanism of either molecule or tetraquark picture, we compute and compare a series of observables for $X(3872)$ in Pb-Pb collisions at the Large Hadron Collider. We find the fireball volume plays a crucial role, leading to a 2-order-of-magnitude difference in the $X(3872)$ yield and a markedly different centrality dependence between hadronic molecules and compact tetraquarks, thus offering a unique opportunity for distinguishing the two scenarios. We also make the first prediction of $X(3872)$ elliptic flow coefficient to be tested by future experimental measurements.

    The shadow of dark matter as a shadow of string theory: String origin of the dipole term

    We point out that the Kalb-Ramond field can couple to the Ramond and Neveu-Schwarz fields of superstring theory in a way that can generate a coupling of the Kalb-Ramond field to dark matter dipole moments. Electroweak dipole dark matter could then arise from the Ramond sector of superstrings with a low string scale up to 120 TeV.

    Valence-Quark Distribution of the Kaon and Pion from Lattice QCD

    Huey-Wen Lin🇺🇸 · Jiunn-Wei Chen🇹🇼 · Zhouyou Fan🇺🇸 · Jian-Hui Zhang🇨🇳 · Rui Zhang🇺🇸

    We present the first lattice-QCD calculation of the kaon valence-quark distribution functions using the large-momentum effective theory (LaMET) approach. The calculation is performed with multiple pion masses with the lightest one around 220 MeV, 2 lattice spacings $a=0.06$ and 0.12 fm, $(M_{\pi }{)}_{\text{min}}L\approx 5.5$, and high statistics ranging from 11,600 to 61,312 measurements. We also calculate the valence-quark distribution of pion and find it to be consistent with the FNAL E615 experimental results, and our ratio of the $u$ quark PDF in the kaon to that in the pion agrees with the CERN NA3 experiment. We also make predictions of the strange-quark distribution of the kaon.

    Discrimination of Dark Matter Mass and Velocity Distribution by Directional Detection

    Keiko I. Nagao🇯🇵

    Velocity distribution of dark matter is assumed to be isotropic in most cases, however, anisotropy is suggested in some simulations. Directional direct detection of dark matter is a hopeful way to discriminate the anisotropy of dark matter velocity distribution. We simulate the dark matter and target scattering in the directional direct detection, and investigate conditions required to discriminate the anisotropy. If dark matter mass is known, $O(10^3)-O(10^4)$ events are required for the discrimination if the dark matter mass is known by other experiments. We also study the case that the dark matter mass is not known, and in analysis using both the recoil energy and the scattering angle data, both the dark matter mass and the anisotropy can be restricted much better than the analysis only with either of them.

    Green Bank and Effelsberg Radio Telescope Searches for Axion Dark Matter Conversion in Neutron Star Magnetospheres

    Joshua W. Foster🇺🇸 · Yonatan Kahn🇺🇸 · Oscar Macias🇯🇵 · Zhiquan Sun🇺🇸 · Ralph P. Eatough🇨🇳 · Vladislav I. Kondratiev🇳🇱 · Wendy M. Peters🇺🇸 · Christoph Weniger🇳🇱 · Benjamin R. Safdi🇺🇸

    Axion dark matter (DM) may convert to radio-frequency electromagnetic radiation in the strong magnetic fields around neutron stars. The radio signature of such a process would be an ultra-narrow spectral peak at a frequency determined by the mass of the axion particle. We analyze data we collected from the Robert C. Byrd Green Bank Telescope in the L-band and the Effelsberg 100-m Telescope in the L-Band and S-band from a number of sources expected to produce bright signals of axion-photon conversion, including the Galactic Center of the Milky Way and the nearby isolated neutron stars RX J0720.4-3125 and RX J0806.4-4123. We find no evidence for axion DM and are able to set some of the strongest constraints to-date on the existence of axion DM in the highly-motivated mass range between ~5-11 $\mu$eV.

    Variations in fundamental constants at the cosmic dawn

    Laura Lopez-Honorez🇧🇪 · Olga Mena🇪🇸 · Sergio Palomares-Ruiz🇪🇸 · Pablo Villanueva-Domingo🇪🇸 · Samuel J. Witte🇪🇸

    The observation of space-time variations in fundamental constants would provide strong evidence for the existence of new light degrees of freedom in the theory of Nature. Robustly constraining such scenarios requires exploiting observations that span different scales and probe the state of the Universe at different epochs. In the context of cosmology, both the cosmic microwave background and the Lyman-$\alpha$ forest have proven to be powerful tools capable of constraining variations in electromagnetism, however at the moment there do not exist cosmological probes capable of bridging the gap between recombination and reionization. In the near future, radio telescopes will attempt to measure the 21cm transition of neutral hydrogen during the epochs of reionization and the cosmic dawn (and potentially the tail end of the dark ages); being inherently sensitive to electromagnetic phenomena, these experiments will offer a unique perspective on space-time variations of the fine-structure constant and the electron mass. We show here that large variations in these fundamental constants would produce features on the 21cm power spectrum that may be distinguishable from astrophysical uncertainties. Furthermore, we forecast the sensitivity for the Square Kilometer Array, and show that the 21cm power spectrum may be able to constrain variations at the level of $\mathcal{O}(10^{-3})$.

    A Consistency Test of EFT Power Countings from Residual Cutoff Dependence

    Harald W. Griesshammer (George Washington U.)🇺🇸

    A method to quantitatively assess the consistency of power-counting proposals in Effective Field Theories (EFT) which are non-perturbative at leading order is presented. The Renormalisation Group evolution of an observable predicts the functional form of its residual cutoff dependence on the breakdown scale of an EFT, on the low-momentum scales, and on the order of the calculation. Passing this test is a necessary but not sufficient consistency criterion for a suggested power counting whose exact nature is disputed. In Chiral Effective Field Theory (ChiEFT) with more than one nucleon, a lack of universally accepted analytic solutions obfuscates the convergence pattern in results. This led to proposals which predict different sets of Low Energy Coefficients (LECs) at the same chiral order, and at times even predict a different ordering long-range contributions. The method may independently check whether an observable is renormalised at a given order, and proves estimates of both the breakdown scale and the momentum-dependent order-by-order convergence pattern. Conversely, it helps identify those LECs (and long-range pieces) which ensure renormalised observables at a given order. I also discuss assumptions and the relation to Wilson's Renormalisation Group; useful observable and cutoff choices; the momentum window with likely best signals; its dependence on the values and forms of cutoffs as well as on the EFT parameters; the impact of fitting LECs to data; and caveats as well as limitations. Since the test is designed to minimise the use of data, it quantitatively falsifies if the EFT has been renormalised consistently. This complements other tests which quantify how an EFT compares to experiment. Its application in particular to the 3P0 and P2-3F2 partial waves of NN scattering in ChiEFT may elucidate persistent power-counting issues.
