Light neutrinos, Dark matter and leptogenesis near electroweak scale and $Z_{4}$ symmetry

Kunal Pandey, Rathin Adhikari

Considering $Z_{4}$ symmetry in Type I seesaw scenario, one could obtain mass-squared differences of light neutrinos, mixings and $C P$ violating phase within $3 I ¨ $ confidence level…

Leptogenesis in exponential $f (R)$ gravity model

Suhail Khan, Ajay Bassi, Rathin Adhikari

We show that gravitational leptogenesis with dynamical $C P T$ breaking in an expanding universe can be reconciled with the exponential $f (R)$ gravity model, which introduces only on…

Explaining Fermions Mass and Mixing Hierarchies through $U (1)_{X}$ and $Z_{2}$ Symmetries

Abdul Rahaman Shaikh, Rathin Adhikari

For understanding the hierarchies of fermion masses and mixing, we extend the Standard Model gauge group with $ U(1)_X $ and $ Z_2 $ symmetry. The field content of the Standard…

Type I seesaw mechanism at TeV scale or below with minimal fields

Kunal Pandey, Rathin Adhikari

A novel scenario is presented within the Type-I seesaw mechanism in which no other beyond Standard Model fields except three heavy right handed neutrinos, have been considered. Lig…
