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- $I I$ seesaw mechanism emp…

$n - n$ Oscillation in $S^{1} / Z_{2} \times Z_{2}^{'}$ Orbifold $S U (5)$ GUT

Ankit Das, Sarthak Duary, Utpal Sarkar

We explore the possibility of $B$ and $B - L$ violating processes, specifically proton decay and neutron-antineutron oscillation, using explicit realization of operators in the $SU(5…
