CPT violation and particle-antiparticle asymmetry in cosmology
read the original abstract
General features of generation of the cosmological charge asymmetry in CPT non-invariant world are discussed. If the effects of CPT violation manifest themselves only in mass differences of particles and antiparticles, the baryon asymmetry of the universe hardly can be explained solely by breaking of CPT invariance. However, CPT non-invariant theories may lead to a new effect of distorting the usual equilibrium distributions. If this takes place, CPT violation may explain the baryon asymmetry of the universe.

CPT Violation, Mirror World and Implications for Baryon Asymmetry
A globally CPT-symmetric paired-universe model with local violations produces inflaton mass splitting that modifies reheating and accounts for observed matter-antimatter asymmetry.
