Abstract
Baryogenesis, through the decays of heavy bosons, was considered to be one of the major successes of the grand unified theories (GUTs). It was then realized that the sphaleron processes erased any baryon asymmetry from the GUT-baryogenesis at a later stage. In this paper, we discuss the idea of resurrecting GUT-baryogenesis [1] in a large class of SO(10) GUTs. Our analysis shows that fast lepton number violating but baryon number conserving processes can partially wash out the GUTbaryogenesis produced lepton and/or baryon asymmetry associated with or without the sphaleron and/or Yukawa interactions.
