Transport equations for chiral fermions to order \hbar and electroweak baryogenesis: Part I
arXiv:hep-ph/0312110 · doi:10.1016/j.aop.2004.06.002
Abstract
This is the first in a series of two papers. We use the Schwinger-Keldysh formalism to derive semiclassical Boltzmann transport equations for massive chiral fermions and scalar particles. Our considerations include complex mass terms and mixing fermion and scalar fields, such that CP-violation is naturally included, rendering the equations particularly suitable for studies of baryogenesis at a first order electroweak phase transition. In part II we discuss the collision terms.
