Leptogenesis: Neutrinos and New Lepton Flavor Violation at the Tev Energy Scale
Ernest Ma
Leptogenesis, i.e. the creation of a lepton asymmetry in the early Universe, may occur through the decay of heavy singlet (right-handed) neutrinos. If we require it not to be erase…

Neutrino Masses and Leptogenesis from R Parity Violation
Ernest Ma
In R parity violating supersymmetry (conserving baryon number B but violating lepton number L), Majorana neutrino masses may arise at tree level, in one loop, and in two loops. The…

Neutrino Masses and Leptogenesis
Ernest Ma
I discuss the connection between neutrino masses and leptogenesis. I use three prime examples: (1) canonical seesaw, (2) triplet Higgs, and (3) parity violation.
