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

2. The eejj excess signal at the LHC and constraints on leptogenesis / Dhuria, Mansi ; Hati, Chandan ; Rangarajan, Raghavan ; Sarkar, Utpal
We review the non-supersymmetric (Extended) Left-Right Symmetric Models (LRSM) and low energy E6-based models to investigate if they can explain both the recently detected excess eejj signal at CMS and leptogenesis. [...]

3. 331 models and grand unification: From minimal SU(5) to minimal SU(6) / Deppisch, Frank F. ; Hati, Chandan ; Patra, Sudhanwa ; Sarkar, Utpal ; et al
We consider the possibility of grand unification of the SU(3)c⊗SU(3)L⊗U(1)X model in an SU(6) gauge unification group. [...]

4. 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. [...]

5. 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 vector-like fermions. [...]

6. 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. [...]

7. B ¯ → D ∗ τ ν ¯ $$ \overline{B}\to {D}^{\left(\ast \right)}\tau \overline{\nu} $$ excesses in ALRSM constrained from B , D decays and D 0 − D ¯ 0 $$ {D}^0-{\overline{D}}^0 $$ mixing / Hati, Chandan ; Kumar, Girish ; Mahajan, Namit
Recent experimental results from the LHCb, BaBar and Belle collaborations on the semitauonic decays of B meson, B ¯ → D ∗ τ ν ¯ $$ \overline{B}\to {D}^{\left(\ast \right)}\tau \overline{\nu} $$ , showing a significant deviation from the Standard Model (SM), hint towards a new physics scenario beyond the SM.
