2023-02-08 Effect of momentum anisotropy on CEP and transport coefficients doi:10.57760/sciencedb.j00186.00014 en At the beginning stage of heavy-ion collision, the pressure In the created fireball along beam direction is greatly lower than along transverse direction. After the rapid expansion of the fireball along the beam direction, the system becomes much colder in the beam direction than the transverse direction, which is finally translated into an anisotropy in the momentum distribution functions of particles. With the two-flavor Nambu–Jona–Lasinio (NJL) model, we study how such momentum anisotropy affects the chiral phase structure, mesonic properties, and transport properties of quark matter.  The dataset includes 24 data files and and provides data for most of the graphs shown in the paper (Nucl.Sci.Tech. 33 (2022) 11, 150).  The dataset contains the following description:(1) The temperature dependence of quark matter at different momentum anisotropy parameters (such as Mass_Quark_xi-0-U_0.dat).(2) The chiral phase diagram at chemical potential-temperature plane for different momentum anisotropy parameters (such as Tem_mu_f3_part1.dat ).(3) The thermal behaviors of cross sections for different quark-(anti)quark scattering process in momentum anisotropic quark matter (such as Total_cross_section_QQ_3.dat).(4) The variation of various transport coefficient (electric conductivity, shear viscosity and Seebeck coefficient) with temperature at different anisotropy parameter (such as shear_viscosity_U_0_3.dat). Note the calculation of Seebeck coefficient is performed at nonzero chemical potential (mu). The dataset provides the associated results for mu=100 MeV.  momentum anisotropy ; critical temperature; transport coefficient He-Xia Zhang PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset http://www.doi.org/10.1007/s41365-022-01129-4 Science Data Bank
