Several mechanisms for the creation of the baryon asymmetry of the universe by nonperturbative electroweak reprocessing of a lepton asymmetry generated in the decay of heavy right handed see-saw (s)neutrinos or scalar condensates are discussed. The importance of eR decoupling is also discussed.
Bibliographical noteFunding Information:
The production of a net baryon asymmetry requires baryon number violating interactions, C and CP violation and the departure from thermal equilibrium\[I\]. Baryon number, C and CP violations are common in guts. The departure of *This work was supported in part by DOE grant DE-AC02-83ER-40105, and by a Pr~idential Young Investigator Award.
