Space-average electromagnetic fields and EM anomaly weighted by energy density in heavy-ion collisions
Irfan Siddique, Xin-Li Sheng, Qun Wang
We study the space-average electromagnetic (EM) fields weighted by the energy density in the central regions of heavy ion collisions. These average quantities can serve as a barome…
From Kadanoff--Baym to Boltzmann equations for massive spin-1/2 fermions
Xin-Li Sheng, Nora Weickgenannt, Enrico Speranza +2
We derive Boltzmann equations for massive spin-1/2 fermions with local and nonlocal collision terms from the Kadanoff--Baym equation in the Schwinger--Keldysh formalism, properly a…
Derivation of the nonlocal collision term in the relativistic Boltzmann equation for massive spin-1/2 particles from quantum field theory
Nora Weickgenannt, Enrico Speranza, Xin-li Sheng +2
We derive the Boltzmann equation and the collision kernel for massive spin-1/2 particles, using the Wigner-function formalism and employing an expansion in powers of . The p…
Electromagnetic fields from the extended Kharzeev-McLerran-Warringa model in relativistic heavy-ion collisions
Yi Chen, Xin-Li Sheng, Guo-Liang Ma
Based on the Kharzeev-McLerran-Warringa (KMW) model that estimates strong electromagnetic (EM) fields generated in relativistic heavy-ion collisions, we generalize the formulas of…
Improved quark coalescence model for spin alignment and polarization of hadrons
Xin-Li Sheng, Qun Wang, Xin-Nian Wang
We propose an improved quark coalescence model for spin alignment of vector mesons and polarization of baryons by spin density matrix with phase space dependence. The spin density…
Kinetic theory with spin: From massive to massless fermions
Xin-Li Sheng, Qun Wang, Xu-Guang Huang
We find that the recently developed kinetic theories with spin for massive and massless fermions are smoothly connected. By introducing a reference-frame vector, we decompose the d…
