Abstract

A new version of cosmological baryon generation is examined. In this scheme the baryon asymmetry is caused by the nonequilibrium decay of an X(leptoquark) and X boson of ∼1016 GeV, which takes place after an equilibrium period of baryon nonconserving two-body reactions. This mechanism imposes a severe constraint on grand unified theories; both upper and lower limits to the unification mass are derived.
