Orbital Phase Spectroscopy of four High Mass X-ray Binary Pulsars to Study the Stellar Wind of the Companion
Sachindra Naik, Uddipan Mukherjee, Biswajit Paul +1
Our work focuses on a comprehensive orbital phase dependent spectroscopy of the four High Mass X-ray Binary Pulsars (HMXBPs) 4U 1538-52, GX 301-2, OAO 1657-415 & Vela X-1. We hereb…
Near Infrared Observations of the novae V2491 Cygni and V597 Puppis
Sachindra Naik, D. P. K. Banerjee, N. M. Ashok
We present results obtained from near-infrared JHK spectroscopic observations of novae V2491 Cyg and V597 Pup in the early declining phases of their 2007 and 2008 outbursts respect…
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…
