Allowable Low-Energy E_6 Subgroups from Leptogenesis
Thomas Hambye, Ernest Ma, Martti Raidal +1
There are only two viable low-energy subgroups: or , whi…
Supersymmetric Triplet Higgs Model of Neutrino Masses and Leptogenesis
Thomas Hambye, Ernest Ma, Utpal Sarkar
We construct a supersymmetric version of the triplet Higgs model for neutrino masses, which can generate a baryon asymmetry of the Universe through lepton-number violation and is c…
1/N_c and epsilon'/epsilon
T. Hambye, P. H. Soldan
We present a recent analysis of epsilon'/epsilon in the 1/N_c expansion. We show that the 1/N_c corrections to the matrix element of Q_6 are large and positive, indicating a Delta…
Leptogenesis from Neutralino Decay with Nonholomorphic R-Parity Violation
Thomas Hambye, Ernest Ma, Utpal Sarkar
In supersymmetric models with lepton-number violation, hence also R-parity violation, it is easy to have realistic neutrino masses, but then leptogenesis becomes difficult to achie…
