    The Relativistic Green's function model and charged-current inclusive neutrino-nucleus scattering at T2K kinematics

    Andrea Meucci🇮🇹 · Carlotta Giusti🇮🇹

    We compare the results of the relativistic Green's function model with the experimental data of the charged-current inclusive differential neutrino-nucleus cross sections published by the T2K Collaboration. The model, which is able to describe both MINERA and MiniBooNE charged-current quasielastic scattering data, underpredicts the inclusive T2K cross sections.

    Impact of the symmetry energy on nuclear pasta phases and crust-core transition in neutron stars

    S. S. Bao🇨🇳 · H. Shen🇨🇳

    We study the impact of the symmetry energy on properties of nuclear pasta phases and crust-core transition in neutron stars. We perform a self-consistent Thomas--Fermi calculation employing the relativistic mean-field model. The properties of pasta phases presented in the inner crust of neutron stars are investigated and the crust-core transition is examined. It is found that the slope of the symmetry energy plays an important role in determining the pasta phase structure and the crust-core transition. The correlation between the symmetry energy slope and the crust-core transition density obtained in the Thomas--Fermi approximation is consistent with that predicted by the liquid-drop model.

    A hybrid model approach for strange and multi-strange hadrons in 2.76 A TeV Pb+Pb collisions

    Xiangrong Zhu🇨🇳 · Fanli Meng (Peking U.)🇨🇳 · Huichao Song🇨🇳 · Yu-Xin Liu (Peking U. & Peking U. CHEP)🇨🇳

    Using the VISHNU hybrid model, we calculate the multiplicity, spectra, and elliptic flow of , and in 2.76 A TeV Pb+Pb collisions. Comparisons between our calculations and the ALICE measurements show that the model generally describes the soft hadron data of these strange and multi-strange hadrons at several centrality bins. Mass ordering of elliptic flow among , K, p, , and has also been studied and discussed. With a nice description of the particle yields, we explore chemical and thermal freeze-out of various hadrons species at the LHC within the framework of the VISHNU hybrid model.

    alignments in neutron-rich Ba with negative-parity pairs

    Yang Lei · Zhengyu Xu

    The shell-model collective-pair truncation with negative-parity pairs is adopted to study the alignment in Ba. The proton -alignment state is predicted as an MeV and s isomer with relatively strong E3 decay channels. The oblately deformed neutron alignment in the yrast band and four negative-parity bands are confirmed, even although two of these negative-parity bands favor the prolate deformation, which directly manifests the unstability of Ba.

    Dilepton production from the quark-gluon plasma using (3+1)-dimensional anisotropic dissipative hydrodynamics

    Radoslaw Ryblewski🇵🇱 · Michael Strickland🇺🇸

    We compute dilepton production from the deconfined phase of the quark-gluon plasma using leading-order (3+1)-dimensional anisotropic hydrodynamics. The anisotropic hydrodynamics equa- tions employed describe the full spatiotemporal evolution of the transverse temperature, spheroidal momentum-space anisotropy parameter, and the associated three-dimensional collective flow of the matter. The momentum-space anisotropy is also taken into account in the computation of the dilepton production rate, allowing for a self-consistent description of dilepton production from the quark-gluon plasma. For our final results, we present predictions for high-energy dilepton yields as a function of invariant mass, transverse momentum, and pair rapidity. We demonstrate that high- energy dilepton production is extremely sensitive to the assumed level of initial momentum-space anisotropy of the quark-gluon plasma. As a result, it may be possible to experimentally constrain the early-time momentum-space anisotropy of the quark-gluon plasma generated in relativistic heavy ion collisions using high-energy dilepton yields.

    Calculation of the Electric and Magnetic Root Mean Squared Radiuses of Proton Based on MIT Bag Model

    Maryam Momeni Feili🇮🇷 · Mahvash Zandi🇮🇷

    The electric and magnetic bag radiuses of the proton can be determined by MIT bag model based on electric and magnetic form factors of the proton. Also we determined electric and magnetic root mean squared radiuses of the proton, using of bag radius and compared with other results suggests a suitable compatibility.
