Leptogenesis with triplet scalars at electroweak scale
Rituparna Ghosh, Biswarup Mukhopadhyaya, Utpal Sarkar
Up until now the works regarding leptogenesis have discussed different mechanisms to explain the observed baryon asymmetry of the universe (BAU). The type- seesaw mechanism emp…
Oscillation in Orbifold GUT
Ankit Das, Sarthak Duary, Utpal Sarkar
We explore the possibility of and violating processes, specifically proton decay and neutron-antineutron oscillation, using explicit realization of operators in the $SU(5…
Probing the Exotic Particle Content Beyond the Standard Model
Ernest Ma, Martti Raidal, Utpal Sarkar
We explore the possible exotic particle content beyond the standard model by examining all its scalar bilinear combinations. We categorize these exotic scalar fields and show that…
CP Violation and Leptogenesis
Andy Acker, Hisashi Kikuchi, Ernest Ma +1
Recently a model of chaotic inflation was proposed, where the right handed sneutrinos drive the baryogenesis. We study some of the details of the model, particularly the aspect of…
