Rescuing leptogenesis parameter space of inverse seesaw
Ananya Mukherjee, Abhijit Kumar Saha
In a pure inverse seesaw framework, achieving a substantial lepton asymmetry that can be converted into the observed baryon asymmetry of the Universe is extremely challenging. The…
Retrieving Inverse Seesaw parameter space for Dirac Phase Leptogenesis
Ananya Mukherjee, Nimmala Narendra
This work addresses the viability of \textit {Dirac phase leptogenesis}, in a scenario where the light Majorana neutrinos acquire masses by the inverse seesaw (ISS) mechanism. We s…
Implications of the Dark-LMA solution for neutrino mass matrices
Monojit Ghosh, Srubabati Goswami, Ananya Mukherjee
In this work we have re-investigated two different kinds of texture zero ansatz of the low energy neutrino mass matrix in view of the Dark-Large-Mixing-Angle (DLMA) solution of the…
A dark clue to seesaw and leptogenesis in a pseudo-Dirac singlet doublet scenario with (non)standard cosmology
Partha Konar, Ananya Mukherjee, Abhijit Kumar Saha +1
We propose an appealing alternative scenario of leptogenesis assisted by dark sector which leads to the baryon asymmetry of the Universe satisfying all theoretical and experimental…
Linking the pseudo-Dirac dark matter and radiative neutrino mass in a singlet doublet scenario
Partha Konar, Ananya Mukherjee, Abhijit Kumar Saha +1
We examine simple extension of the standard model with a pair of fermions, one singlet and a doublet, in a common thread linking the dark matter problem with the smallness of neutr…
Realization of the minimal extended seesaw mechanism and the type neutrino mixing
R. Krishnan, Ananya Mukherjee, Srubabati Goswami
We construct a neutrino mass model based on the flavour symmetry group which accommodates a light sterile neutrino in the minimal extended see…
