Neutrinoless double beta decay in leftright symmetric models with a universal seesaw mechanism
/ Deppisch, Frank F. ; Hati, Chandan ; Patra, Sudhanwa ; Pritimita, Prativa ; et al
We discuss a class of leftright symmetric theories with a universal seesaw mechanism for fermion masses and mixing and the implications for neutrinoless double beta ($0\nu \beta \beta $) decay where neutrino masses are governed by natural typeII seesaw dominance. [...]

The eejj excess signal at the LHC and constraints on leptogenesis
/ Dhuria, Mansi ; Hati, Chandan ; Rangarajan, Raghavan ; Sarkar, Utpal
We review the nonsupersymmetric (Extended) LeftRight Symmetric Models (LRSM) and low energy E6based models to investigate if they can explain both the recently detected excess eejj signal at CMS and leptogenesis. [...]

Neutrino dark energy and leptogenesis with TeV scale triplets
/ Hati, Chandan ; Sarkar, Utpal
We propose a realization of mass varying neutrino dark energy in two extensions of the Standard Model (SM) with a dynamical neutrino mass related to the acceleron field while satisfying the naturalness. [...]

Implications of the diphoton excess on left–right models and gauge unification
/ Deppisch, Frank F. ; Hati, Chandan ; Patra, Sudhanwa ; Pritimita, Prativa ; et al
The recent diphoton excess signal at an invariant mass of 750 GeV can be interpreted in the framework of left–right symmetric models with additional scalar singlets and vectorlike fermions. [...]

Moduli induced cogenesis of baryon asymmetry and dark matter
/ Dhuria, Mansi ; Hati, Chandan ; Sarkar, Utpal
We study a cogenesis mechanism in which the observed baryon asymmetry of the universe and the dark matter abundance can be produced simultaneously at low reheating temperature without violating baryon number in the fundamental interactions. [...]
