Neutrino masses, leptogenesis and dark matter in hybrid seesaw
Pei-Hong Gu, M. Hirsch, Utpal Sarkar +1
We suggest a hybrid seesaw model where relatively ``light''right-handed neutrinos give no contribution to the neutrino mass matrix due to a special symmetry. This allows their Yuka…
Lepton Flavour Violating Heavy Higgs Decays Within the nuMSSM and Their Detection at the LHC
J. L. Diaz-Cruz, Dilip Kumar Ghosh, S. Moretti
Within the MSSM, a Minimal Supersymmetric neutrino See-saw Model, Lepton Flavour Violating Higgs couplings are strongly enhanced at large ($\gsim30$), which can lead to…
Minimal Seesaw Textures with Two Heavy Neutrinos
Srubabati Goswami, Atsushi Watanabe
We systematically analyze the Dirac and the Majorana mass matrices in seesaw models with two heavy right-handed neutrinos. We perform thorough classification of the vanishing matri…
Resolving the Mass Hierarchy with Atmospheric Neutrinos using a Liquid Argon Detector
Raj Gandhi, Pomita Ghoshal, Srubabati Goswami +1
We explore the potential offered by large-mass Liquid Argon detectors for determination of the sign of Delta m_{31}^2, or the neutrino mass hierarchy, through interactions of atmos…
Signature of short distance physics on inflation power spectrum and CMB anisotropy
Suratna Das, Subhendra Mohanty
The inflaton field responsible for inflation may not be a canonical fundamental scalar. It is possible that the inflaton is a composite of fermions or it may have a decay width. In…
Natural inflation at the GUT scale
Subhendra Mohanty, Akhilesh Nautiyal
Natural inflation driven by Pseudo-Nambu-Goldstone bosons have a problem that the nearly scale invariant spectrum of density perturbations is attained only when the symmetry breaki…
