Leptogenesis is a class of scenarios where the baryon asymmetry of the Universe is
produced from a lepton asymmetry generated in the decays of heavy singlet neutrinos. We …

We review the cosmological implications of the flat directions of the minimally
supersymmetric standard model (MSSM). We describe how field condensates are created …

We study the scenario of thermal leptogenesis in which the leptonic asymmetries are
resonantly enhanced through the mixing of nearly degenerate heavy Majorana neutrinos …

During the process of thermal leptogenesis temperature decreases by about one order of
magnitude while the baryon asymmetry is generated. We present an analytical description of …

This paper is a review of the present status of neutrino mass physics, which grew out of an
APS sponsored study of neutrinos in 2004. After a discussion of the present knowledge of …

We study the implications of thermal leptogenesis for neutrino parameters. Assuming that
decays of N1, the lightest of the heavy Majorana neutrinos, initiate baryogenesis, we show …

We derive simple analytical formulae for the renormalization group running of neutrino
masses, leptonic mixing angles and CP phases, which allow an easy understanding of the …

Interactions of heavy Majorana neutrinos in the thermal phase of the early universe may be
the origin of the cosmological matter–antimatter asymmetry. This mechanism of …

We study the possibility of cogenesis of baryon and dark matter (DM) from the out-of-
equilibrium CP violating decay of right handed neutrino (RHN) that are dominantly of non …

Given its briefness and predictability, the minimal seesaw—a simplified version of the
canonical seesaw mechanism with only two right-handed neutrino fields—has been studied …
