论文摘要
我们计算非均匀经典电磁场中带电的Spin-1颗粒的Wigner函数，以$ \ hbar $中的功率系列为一阶。从这种形式主义获得的标量分布函数的Boltzmann方程与以前的Spin-1/2颗粒计算一致。特别是，我们恢复了两倍的Mathisson力，正确反映了媒介中的较高偶极矩。获得了矢量和张量自由度的演化方程，并讨论了全球平衡。
We calculate the Wigner function for charged spin-1 particles in inhomogeneous classical electromagnetic fields, going to first order in a power series in $\hbar$. The Boltzmann equation for the scalar distribution function obtained from this formalism agrees with previous calculations for spin-1/2 particles. In particular, we recover a Mathisson force of twice the magnitude, correctly reflecting the higher dipole moment of vector mesons. Evolution equations for vector and tensor degrees of freedom are obtained, and global equilibrium is discussed.
