Quantum kinetic theory with interactions for massive vector bosons

Abstract

We present a derivation of quantum kinetic theory for massive spin-1 particles from the Wigner-function formalism up to first order in an $\hslash$-expansion, including a general interaction term. Both local and nonlocal contributions are computed in a covariant fashion. It is shown that, up to first order in $\hslash$, the collision term takes the same form as in the case of spin-1/2 particles.
