   Mu to e gamma and matching at mW

   Sacha Davidson🇫🇷

   Several experiments search for \mu - e flavour change, for instance in \mu ->e conversion, \mu-> e \gamma, and \mu -> 3e. This paper studies how to translate these experimental constraints from low energy to a New Physics scale M >> mW. A basis of QCD and QED-invariant operators (as appropriate below mW) is constructed, then run to mW with one-loop RGEs of QCD and QED. At mW, these operators are matched onto SU(2)-invariant dimension-six operators, which can continue to run up with electroweak RGEs. As an example, the \mu-> e \gamma bound is translated to the scale M, where it constrains two sums of operators. The constraints differ from those obtained in previous EFT analyses of \mu -> e \gamma, but reproduce the expected bounds on flavour-changing interactions of the Z and the Higgs, because the matching at mW is pragmatically performed to the loop order required to get the "leading" contribution.

   Photo-production of a 750 GeV di-photon resonance mediated by Kaluza-Klein leptons in the loop

   Steven Abel🇬🇧 · Valentin V. Khoze🇬🇧

   We consider the phenomenology of a 750 GeV resonance X which can be produced at the LHC by only photon fusion and subsequently decay into di-photons. We propose that the spin-zero state X is coupled to a heavy lepton that lives in the bulk of a higher-dimensional theory and interacts only with the photons of the Standard Model. We compute the di-photon rate in these models with two and more compact extra dimensions and demonstrate that they allow for a compelling explanation of the di-photon excess recently observed by the ATLAS and CMS collaborations. The central role in our approach is played by the summation over the Kaluza-Klein modes of the new leptons, thus providing a significant enhancement of the $X\to \gamma \gamma$ loops for the production and decay subprocesses. It is expected that the jet activity accompanying these purely electromagnetic (at the partonic level) processes is numerically suppressed by factors such as ${\alpha }_{em}^2{C}_{q\bar{q}}/C_{\gamma \gamma }\sim 10^{-3}$.

   The Vector-like Twin Higgs

   Nathaniel Craig🇺🇸 · Simon Knapen🇺🇸 · Pietro Longhi🇸🇪 · Matthew Strassler🇺🇸

   We present a version of the twin Higgs mechanism with vector-like top partners. In this setup all gauge anomalies automatically cancel, even without twin leptons. The matter content of the most minimal twin sector is therefore just two twin tops and one twin bottom. The LHC phenomenology, illustrated with two example models, is dominated by twin glueball decays, possibly in association with Higgs bosons. We further construct an explicit four-dimensional UV completion and discuss a variety of UV completions relevant for both vector-like and fraternal twin Higgs models.

   N-Relaxion: Large Field Excursions from a Few Site Relaxion Model

   Nayara Fonseca🇧🇷 · Leonardo de Lima🇩🇪 · Camila S. Machado🇧🇷 · Ricardo D. Matheus🇧🇷

   Relaxion models are an interesting new avenue to explain the radiative stability of the Standard Model scalar sector. They require very large field excursions, which are difficult to generate in a consistent UV completion and to reconcile with the compact field space of the relaxion. We propose an N-site model which naturally generates the large decay constant needed to address these issues. Our model offers distinct advantages with respect to previous proposals: the construction involves non-abelian fields, allowing for controlled high energy behaviour and more model building possibilities, both in particle physics and inflationary models, and also admits a continuum limit when the number of sites is large, which may be interpreted as a warped extra dimension.

   The production of a diphoton resonance via photon-photon fusion

   L. A. Harland-Lang🇬🇧 · V. A. Khoze🇬🇧 · M. G. Ryskin🇷🇺

   Motivated by the recent LHC observation of an excess of diphoton events around an invariant mass of 750 GeV, we discuss the possibility that this is due to the decay of a new scalar or pseudoscalar resonance dominantly produced via photon-photon fusion. We present a precise calculation of the corresponding photon-photon luminosity in the inclusive and exclusive scenarios, and demonstrate that the theoretical uncertainties associated with these are small. In the inclusive channel, we show how simple cuts on the final state may help to isolate the photon-photon induced cross section from any gluon-gluon or vector boson fusion induced contribution. In the exclusive case, that is where both protons remain intact after the collision, we present a precise cross section evaluation and show how this mode is sensitive to the parity of the object, as well as potential $CP$-violating effects. We also comment on the case of heavy-ion collisions and consider the production of new heavy colourless fermions, which may couple to such a resonance.

   Resummation of electroweak Sudakov logarithms for real radiation

   Christian W Bauer🇺🇸 · Nicolas Ferland🇺🇸

   Using the known resummation of virtual corrections together with knowledge of the leading-log structure of real radiation in a parton shower, we derive analytic expressions for the resummed real radiation after they have been integrated over all of phase space. Performing a numerical analysis for both the 13 TeV LHC and a 100 TeV $pp$ collider, we show that resummation of the real corrections is at least as important as resummation of the virtual corrections, and that this resummation has a sizable effect for partonic center of mass energies exceeding $\sqrt{s}=\mathcal{O}$(few TeV). For partonic center of mass energies $\sqrt{s}\gtrsim$ 10 TeV, which can be reached at a 100 TeV collider, resummation becomes an O(1) effect and needs to be included even for rough estimates of the cross-sections.

   Electron Beam Single-Spin Asymmetries in the Resonance Region with Final Hadrons Observed

   Brandon Buncher🇺🇸 · Carl E. Carlson (William and Mary)🇺🇸

   We study beam-transverse and normal single-spin asymmetry for electron-proton inelastic scattering in the resonance region for the case where a pion is observed in the final state. There is no beam single-spin asymmetry if the observed particle has single-photon exchange as its only interaction, but this is naturally circumvented when one observes a strongly interacting final state particle. The asymmetries are not large as there is an electron mass divided by momentum transfer suppression. We present results for the cases where the final electron and a pion are both observed, with asymmetries of order tens of ppm, and where only a final pion is observed, with asymmetries of order one ppm.

   Simplified Models for Higgs Physics: Singlet Scalar and Vector-like Quark Phenomenology

   Matthew J. Dolan🇦🇺 · J.L. Hewett🇺🇸 · M. Krämer🇩🇪 · T.G. Rizzo🇺🇸

   Simplified models provide a useful tool to conduct the search and exploration of physics beyond the Standard Model in a model-independent fashion. In this work we consider the complementarity of indirect searches for new physics in Higgs couplings and distributions with direct searches for new particles, using a simplified model which includes a new singlet scalar resonance and vector-like fermions that can mix with the SM top-quark. We fit this model to the combined ATLAS and CMS 125 GeV Higgs production and coupling measurements and other precision electroweak constraints, and explore in detail the effects of the new matter content upon Higgs production and kinematics. We highlight some novel features and decay modes of the top partner phenomenology, and discuss prospects for Run II.

   750 GeV Diphoton Resonance from Singlets in an Exceptional Supersymmetric Standard Model

   S. F. King🇬🇧 · R. Nevzorov🇦🇺

   The 750-760 GeV diphoton resonance may be identified as one or two scalars and/or one or two pseudoscalars contained in the two singlet superfields S_{1,2} arising from the three 27-dimensional representations of E_6 . The three 27s also contain three copies of colour-triplet charge \mp 1/3 vector-like fermions D,\bar{D} and two copies of charged inert Higgsinos \tilde{H}^{+},\tilde{H}^{-} to which the singlets S_{1,2} may couple. We propose a variant of the E_6SSM where the third singlet S_3 breaks a gauged U(1)_N above the TeV scale, predicting Z'_N, D,\bar{D}, \tilde{H}^{+},\tilde{H}^{-} at LHC Run 2, leaving the two lighter singlets S_{1,2} with masses around 750 GeV. We calculate the branching ratios and cross-sections for the two scalar and two pseudoscalar states associated with the S_{1,2} singlets, including possible degeneracies and maximal mixing, subject to the constraint that their couplings remain perturbative up to the unification scale.

    Atomic ionization by sterile-to-active neutrino conversion and constraints on dark matter sterile neutrinos with germanium detectors

    Jiunn-Wei Chen🇹🇼 · Hsin-Chang Chi🇹🇼 · Shin-Ted Lin🇨🇳 · C.-P. Liu🇹🇼 · Lakhwinder Singh🇹🇼 · Henry T. Wong🇹🇼 · Chih-Liang Wu🇹🇼 · Chih-Pan Wu🇹🇼

    The transition magnetic moment of a sterile-to-active neutrino conversion gives rise to not only radiative decay of a sterile neutrino, but also its non-standard interaction (NSI) with matter. For sterile neutrinos of keV-mass as dark matter candidates, their decay signals are actively searched for in cosmic X-ray spectra. In this work, we consider the NSI that leads to atomic ionization, which can be detected by direct dark matter experiments. It is found that this inelastic scattering process for a nonrelativistic sterile neutrino has a pronounced enhancement in the differential cross section at energy transfer about half of its mass, manifesting experimentally as peaks in the measurable energy spectra. The enhancement effects gradually smear out as the sterile neutrino becomes relativistic. Using data taken with germanium detectors that have fine energy resolution in keV and sub-keV regimes, constraints on sterile neutrino mass and its transition magnetic moment are derived and compared with those from astrophysical observations.

    The properties of the Higgs bosons and Pair Production of the SM-like Higgs Boson in \lambda-SUSY at the LHC

    Haijing Zhou🇨🇳 · Zhaoxia Heng🇨🇳 · Dongwei Li🇨🇳

    Compared with the MSSM or the NMSSM with a low \lambda, \lambda-SUSY theory with a large \lambda around one has been deemed as a most natural realization of NMSSM. In this work, we treat the next-to-lightest CP-even Higgs boson as the SM-like Higgs boson in \lambda-SUSY and study the properties of the Higgs bosons and the pair production of the SM-like Higgs boson by considering various experiment constraints. We find that naturalness plays an important role in selecting the parameter space of \lambda-SUSY. In the most natural region of parameter space, the triple self coupling of the SM-like Higgs boson compared with its SM prediction may get enhanced by a factor about 7, and the most dominant contribution to the Higgs pair production comes from the triple self coupling of the SM-like Higgs boson and the production rate can be greatly enhanced, maximally 10 times larger than the SM prediction.

    A $Z^{\prime }$ Model for $b\to s\ell \bar{\ell }$ Flavour Anomalies

    Cheng-Wei Chiang🇹🇼 · Xiao-Gang He🇨🇳 · German Valencia🇦🇺

    We study the implications of flavour-changing neutral currents (FCNC's) in a model with the $SU(2{)}_l\times SU(2{)}_h\times U(1{)}_Y$ electroweak gauge symmetry for several anomalies appearing in $b\to s\ell \bar{\ell }$ induced $B$ decays in LHCb data. In this model, $SU(2{)}_l$ and $SU(2{)}_h$ govern the left-handed fermions in the first two generations and the third generation, respectively. The physical $Z$ and $Z^{\prime }$ generate the $b\to s$ transition at tree level, leading to additional contributions to the $b\to s$ semileptonic operators ${\mathcal{O}}_{9,10}$. We find that although $B_s$-${\bar{B}}_s$ mixing constrains the parameters severely, the model can produce values of ${\mathcal{C}}_{9,10}^{\mathrm{NP}}$ in the range determined by Descotes-Genon {\it et. al.} in Ref.~\cite{Descotes-Genon:2015uva} for this scenario to improve the global fit of observables in decays induced by the $b\to s\mu \bar{\mu }$ transition. The $Z^{\prime }$ boson in this model also generates tree-level FCNC's for the leptonic interactions that can accommodate the experimental central value of $R_K=\mathcal{B}(B\to K\mu \bar{\mu })/\mathcal{B}(B\to Ke\bar{e})=0.75$. In this case, the model predicts sizeable branching ratios for $B\to Ke\bar{\tau }$, $B\to K\tau \bar{e}$, and an enhancement of $B\to K\tau \bar{\tau }$ with respect to its SM value.

    Re-examining the significance of the 750 GeV diphoton excess at ATLAS

    Bradley J. Kavanagh🇫🇷

    The excess seen in the diphoton channel at around 750 GeV by both ATLAS and CMS has caused a great deal of excitement in the particle physics community. However, there has recently been much discussion about uncertainties in the significance of the peak seen by the ATLAS experiment. In this note, we aim to estimate this significance using a range of possible parametrisations for the smooth diphoton background. We obtain a local significance close to that reported by ATLAS and further demonstrate that the significance of the excess is not substantially reduced when more complicated background functions are considered. In particular, the background contribution is strongly constrained by the small numbers of events at large diphoton invariant mass. Future data releases will improve constraints on the diphoton background, as well as clarifying the true nature of the 750 GeV excess.

    Generalized Zee-Babu model with 750 GeV Diphoton Resonance

    Takaaki Nomura🇰🇷 · Hiroshi Okada🇹🇼

    We propose a generalized Zee-Babu model with a global $U(1)$ B-L symmetry, in which we classify the model in terms of the number of the hypercharge $N/2$ of the isospin doublet exotic charged fermions. Corresponding to each of the number of $N$, we need to introduce some multiply charged bosons in order to make the exotic fields decay into the standard model fields. We also discuss the muon anomalous magnetic moment and the diphoton excess depending on $N$, and we show what kind of models are in favor of these phenomenologies.

    Off-equilibrium sphaleron transitions in the Glasma

    M. Mace🇺🇸 · S. Schlichting🇺🇸 · R. Venugopalan🇺🇸

    We perform first classical-statistical real time lattice simulations of topological transitions in the non-equilibrium Glasma of weakly coupled but highly occupied gauge fields created immediately after the collision of ultra-relativistic nuclei. Simplifying our description by employing SU(2) gauge fields, and neglecting their longitudinal expansion, we find that the rate of topological transitions is initially strongly enhanced relative to the thermal sphaleron transition rate and decays with time during the thermalization process. Qualitative features of the time dependence of this non-equilibrium transition rate can be understood when expressed in terms of the magnetic screening length, which we also extract non-perturbatively. A detailed investigation of auto-correlation functions of the Chern-Simons number ($N_{CS}$) reveals non-Markovian features of the evolution distinct from previous simulations of non-Abelian plasmas in thermal equilibrium.

    Note on Spin-2 Particle Interpretation of the 750~GeV Diphoton Excess

    Chao-Qiang Geng🇨🇳 · Da Huang🇹🇼

    We explore the possibility to explain the 750 GeV diphoton excess recently measured by ATLAS and CMS collaborations in terms of a massive spin-2 particle. In particular, we consider the case in which the top-quark loops can give the similar amplitudes as the tree-level contributions to the diphoton and digluon channels. Such a scenario can be naturally realized in the generalized warped extra dimension models. As a result, the parameter space favored by the diphoton data implies that the top-quark loop contribution can compete to and even dominate over the tree-level amplitude in the spin-2 particle production via the gluon-gluon fusion process. Similar results are obtained for the case in which the spin-2 particle induces large invisible decay branching ratios, as indicated by the ATLAS data.

    Lepton Flavour Violation in Hadron Decays of the Tau Lepton in the Simplest Little Higgs Model

    A. Lami🇪🇸 · J. Portoles (IFIC, Valencia)🇪🇸 · P. Roig (Cinvestav, Mexico)🇲🇽

    We study Lepton Flavour Violating hadron decays of the tau lepton within the Simplest Little Higgs model. Namely we consider $\tau \to \mu (P,V,PP)$ where $P$ and $V$ are short for a pseudoscalar and a vector meson. We find that, in the most positive scenarios, branching ratios for these processes are predicted to be, at least, four orders of magnitude smaller than present experimental bounds.

    Diphoton excess at 750 GeV and LHC constraints in models with vector-like particles

    Junichiro Kawamura🇯🇵 · Yuji Omura🇯🇵

    Recently, the ATLAS and CMS collaborations report excesses around $750$ GeV in the diphoton channels. This might be the evidence which reveals new physics beyond the Standard Model. In this paper, we consider models with a $750$ GeV scalar and vector-like particles, which couple each other through Yukawa couplings. The diphoton decay of the scalar is enhanced by the loop diagrams involving the extra colored particles. We investigate not only the setup required by the excesses, but also the LHC constraints, especially concerned with the vector-like particles. We consider the scenario that the extra colored particles decay to quarks and a dark matter (DM) via Yukawa couplings. Then, the signals from the vector-like particles are dijet, $b\overline{b}$ and/or $t\overline{t}$ with large missing energy. We discuss two possibilities for the setups: One is a model with vector-like fermions and a scalar DM, and the other is a model with vector-like scalars and a fermionic DM. We suggest the parameter region favored by the excess in the each case, and study the constraints based on the latest LHC results at $\sqrt{s}=8$ TeV and $13$ TeV. We conclude that the favored region is almost excluded by the LHC bounds, especially when the $750$ GeV scalar dominantly decays to DMs. The mass differences between the vector-like particles and the DM should be less than $\mathcal{O}(100)$ GeV ($\mathcal{O}(10)$ GeV) to realize the large diphoton signal and the large decay width, if the extra colored particle only decays to a top (bottom) quark and a DM. Otherwise, these scenarios are already excluded by the latest LHC results.

A few results for the pp -> ttj + X production process at the LHC with sqrt(s) = 8 TeV are also shown. All results have been obtained using the Nagy-Soper parton shower implementation in the DEDUCTOR program together with the HELAC-NLO framework.

    Measuring polarizations of bottom, charm, strange, up and down quarks in top decays

    Yevgeny Kats🇮🇱

    Standard Model $t\bar{t}$ samples in ATLAS and CMS provide an opportunity to conduct measurements of the polarization of quarks produced in top-quark decays. The bottom quarks from the $t\to W^{+}b$ decays, as well as the charm, strange, up and down quarks from the subsequent $W^{+}\to c\bar{s},u\bar{d}$ decays, are polarized. When a polarized quark hadronizes to a baryon, its polarization is partly preserved, and is reflected in the angular distributions of the baryon decay products. For the strange and bottom quarks, this effect has already been seen in hadronic $Z$ decays at LEP. In Run 2 of the LHC, $t\bar{t}$ samples will have comparable statistics and several advantages from the point of view of flavor tagging. We propose strategies for such measurements in ATLAS and CMS. We estimate that precision of order $10\%$ is attainable for the polarizations of the strange, charm and bottom quarks. In future higher-statistics runs, polarizations of up and down quarks might be measurable as well.

    What is $\Delta m_{ee}^2$ ?

    Stephen Parke🇺🇸

    The current short baseline reactor experiments, Daya Bay and RENO (Double Chooz) have measured (or are capable of measuring) an effective $\Delta m^2$ associated with the atmospheric oscillation scale of 0.5 km/MeV in electron anti-neutrino disappearance. In this paper, I compare and contrast the different definitions of such an effective $\Delta m^2$ and argue that the simple, L/E independent, definition given by $\Delta m_{ee}^2\equiv {\cos }^2{\theta }_{12}\Delta m_{31}^2+{\sin }^2{\theta }_{12}\Delta m_{32}^2$, i.e. "the ${\nu }_e$ weighted average of $\Delta m_{31}^2$ and $\Delta m_{32}^2$," is superior to all other definitions and is useful for both short baseline experiments mentioned above and for the future medium baseline experiments JUNO and RENO 50.

Becker-Szendy {\em et al.}\cite{BZ} depended heavily on the Lee and Koh flux\cite{LeeKoh} which was noted as erroneous in Gaisser {\em et al.}\cite{Bug}. This makes the results of Becker-Szendy {\em et al.}\cite{BZ} unreliable.

No significant evidence of the spectral modification due to isotropic Lorentz-violation was found, and a two-sided limit of $-2.65\times 10^{-5}\text{GeV}<{\mathring{a}}_{\text{of}}^{(3)}<7.60\times 10^{-6}\text{GeV}$ (90% C.L.) is placed on the relevant coefficient within the Standard-Model Extension (SME). This is the first experimental study of the effect of the SME-defined oscillation-free and momentum-independent neutrino coupling operator on the double beta decay process.

    Cosmological Constraint on the Light Gravitino Mass from CMB Lensing and Cosmic Shear

    Ken Osato🇯🇵 · Toyokazu Sekiguchi🇰🇷 · Masato Shirasaki🇯🇵 · Ayuki Kamada🇺🇸 · Naoki Yoshida🇯🇵

    Light gravitinos of mass $\lesssim \mathcal{O}(10)$ eV are of particular interest in cosmology, offering various baryogenesis scenarios without suffering from the cosmological gravitino problem. The gravitino may contribute considerably to the total matter content of the Universe and affect structure formation from early to present epochs. After the gravitinos decouple from other particles in the early Universe, they free-stream and consequently suppress density fluctuations of (sub-)galactic length scales. Observations of structure at the relevant length-scales can be used to infer or constrain the mass and the abundance of light gravitinos. We derive constraints on the light gravitino mass using the data of cosmic microwave background (CMB) lensing from Planck and of cosmic shear from the Canada France Hawaii Lensing Survey, combined with analyses of the primary CMB anisotropies and the signature of baryon acoustic oscillations in galaxy distributions. The obtained constraint on the gravitino mass is $m_{3/2}<4.7$ eV (95% C.L.), which is substantially tighter than the previous constraint from clustering analysis of Ly-$\alpha$ forests.

    The QCD Critical Point and Related Observables

    Marlene Nahrgang🇺🇸

    The search for the critical point of QCD in heavy-ion collision experiments has sparked enormous interest with the completion of phase I of the RHIC beam energy scan. Here, I review the basics of the thermodynamics of the QCD phase transition and its implications for experimental multiplicity fluctuations in heavy-ion collisions. Several sources of noncritical fluctuations impact the observables and need to be understood in addition to the critical phenomena. Recent progress has been made in dynamical modeling of critical fluctuations, which ultimately is indispensable to understand potential signals of the QCD critical point in heavy-ion collision.
