Probing Seesaw in an Adjoint SUSY SU(5) Model at LHC
Ram Lal Awasthi, Sandhya Choubey, Manimala Mitra
The SU(5) GUT model extended with fermions in the adjoint representation predicts triplet fermions in the 100 GeV mass range, opening up the possibility of testing seesaw at…
Signatures of collective and matter effects on supernova neutrinos at large detectors
Sandhya Choubey, Basudeb Dasgupta, Amol Dighe +1
We calculate the expected galactic supernova neutrino signal at large next-generation underground detectors. At different epochs after the explosion, the primary fluxes can be quit…
Ultra-high neutrino fluxes as a probe for non-standard physics
Atri Bhattacharya, Sandhya Choubey, Raj Gandhi +1
We examine how light neutrinos coming from distant active galactic nuclei (AGN) and similar high energy sources may be used as tools to probe non-standard physics. In particular we…
On the Observability of Collective Flavor Oscillations in Diffuse Supernova Neutrino Background
Sovan Chakraborty, Sandhya Choubey, Kamales Kar
Collective flavor oscillations are known to bring multiple splits in the supernova (SN) neutrino and antineutrino spectra. These spectral splits depend not only on the mass hierarc…
On the Vanishing of the CP Asymmetry in Leptogenesis due to Form Dominance
Sandhya Choubey, S. F. King, Manimala Mitra
We emphasize that the vanishing of the CP asymmetry in leptogenesis, previously observed for models with tri-bimaximal mixing and family symmetry, may be traced to a property of th…
