Quantum kinetic theory for spin-1/2 fermions in Wigner function formalism
Jian-Hua Gao, Zuo-Tang Liang, Qun Wang
We give a brief overview of the kinetic theory for spin-1/2 fermions in Wigner function formulism. The chiral and spin kinetic equations can be derived from equations for Wigner fu…
Global polarization effect and spin-orbit coupling in strong interaction
Jian-Hua Gao, Zuo-Tang Liang, Qun Wang +1
In non-central high energy heavy ion collisions the colliding system posses a huge orbital angular momentum in the direction opposite to the normal of the reaction plane. Due to th…
Second-order Charge Currents and Stress Tensor in Chiral System
Shi-Zheng Yang, Jian-Hua Gao, Zuo-Tang Liang +1
We solve the Wigner equation for massless spin-1/2 charged fermions near global equilibrium. The Wigner function can be obtained order by order in the power expansion of the vortic…
The Spin Alignment of Vector Mesons in High Energy pp Collisions
Kai-bao Chen, Zuo-tang Liang, Yu-kun Song +1
The spin alignment of vector meson produced in high energy reactions is determined by the spin-dependent fragmentation function that is shown to be independent of…
