Neutrino dark energy and leptogenesis with TeV scale triplets

Chandan Hati, Utpal Sarkar

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 satis…

Moduli induced cogenesis of baryon asymmetry and dark matter

Mansi Dhuria, Chandan Hati, Utpal Sarkar

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 with…

Reconciling the 2 TeV Excesses at the LHC in a Linear Seesaw Left-Right Model

Frank F. Deppisch, Lukas Graf, Suchita Kulkarni +4

We interpret the 2 TeV excesses at the LHC in a left-right symmetric model with Higgs doublets and spontaneous $D$ -parity violation. The light neutrino masses are understood via a…

Explaining the CMS excesses, baryogenesis and neutrino masses in $E_{6}$ motivated $U (1)_{N}$ model

Mansi Dhuria, Chandan Hati, Utpal Sarkar

We study the superstring inspired $E_{6}$ model motivated $U (1)_{N}$ extension of the supersymmetric standard model to explore the possibility of explaining the recent excess CMS e…

The $ee j j$ Excess Signal at the LHC and Constraints on Leptogenesis

Mansi Dhuria, Chandan Hati, Raghavan Rangarajan +1

We review the non-supersymmetric (Extended) Left-Right Symmetric Models (LRSM) and low energy $E_{6}$ -based models to investigate if they can explain both the recently detected exces…

Falsifying leptogenesis for a TeV scale $W_{R}^{\pm}$ at the LHC

Mansi Dhuria, Chandan Hati, Raghavan Rangarajan +1

We point out that the discovery of a right-handed charged gauge boson $W_{R}^{\pm}$ with mass of around a few TeV, for example through a signal of two leptons and two jets that has bee…

Explaining the CMS $ee j j$ and $e missing p_{T} jj$ excess and leptogenesis in superstring inspired $E_{6}$ models

Mansi Dhuria, Chandan Hati, Raghavan Rangarajan +1

We show that superstring inspired $E_{6}$ models can explain both the recently detected excess $ee j j$ and $e missing p_{T} jj$ signals at CMS, and also allow for leptogenesis.…
