    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.
