  • Dhuria, Mansi; Hati, Chandan; Rangarajan, Raghavan; Sarkar, Utpal (IOP Publishing, 2015-09)
    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. The ...
  • Dhuria, Mansi; Hati, Chandan; Rangarajan, Raghavan; Sarkar, Utpal (Cornell University Library, 2015-01)
    We show that superstring inspired E6 models can explain both the recently detected excess eejj and $e \slashed p_T jj$ signals at CMS, and also allow for leptogenesis. Working in a R-parity conserving low energy supersymmetric ...
  • Dhuria, Mansi; Hati, Chandan; Rangarajan, Raghavan; Sarkar, Utpal (American Physical Society, 2015-03)
    We show that superstring-inspired E6 models can explain both the recently detected excess eejj and epTjj signals at CMS and also allow for leptogenesis. Working in an R-parity conserving, low-energy supersymmetric effective ...
  • Dhuria, Mansi; Hati, Chandan; Rangarajan, Raghavan; Sarkar, Utpal (American Physical Society, 2015)
    We point out that the discovery of a right-handed charged gauge boson W±R with mass of around a few TeV, for example through a signal of two leptons and two jets that has been reported by CMS to have a 2.8σ local excess ...
  • Dhuria, Mansi; Hati, Chandan; Rangarajan, Raghavan; Sarkar, Utpal (Cornell University Library, 2015-03)
    We study the left-right symmetric extensions of the Standard Model (LRSM) and point out that the discovery of a right-handed charged gauge boson W±R with mass in the TeV range will have profound consequences for leptogenesis. ...
  • Arya, Richa; Mahajan, Namit; Rangarajan, Raghavan (Cornell University Library, 2016-08)
    We study the production of spin 1/2 gravitinos in a thermal Universe. Taking into account supersymmetry breaking due to the finite thermal energy density of the Universe, there is a large enhancement in the cross section ...

    We study the production of spin 1/2 gravitinos in a thermal Universe. Taking into account supersymmetry breaking due to the finite thermal energy density of the Universe, there is a large enhancement in the cross section ...
  • Arya, Richa; Dasgupta, Arnab; Goswami, Gaurav; Prasad, Jayanti; Rangarajan, Raghavan (IOP Publishing, 2018-02)
    We revisit the constraints that Planck 2015 temperature, polarization and lensing data impose on the parameters of warm inflation. To this end, we study warm inflation driven by a single scalar field with a quartic self ...
