Supernova neutrino detection through neutron emission by nuclei
Pijushpani Bhattacharjee, Kamales Kar
Neutrinos from core collapse supernovae can excite nuclei of some detector materials beyond their neutron emission thresholds. Detection of these neutrons can give valuable informa…
Inelastic charged current interaction of supernova neutrinos in two-phase liquid xenon dark matter detectors
Pijushpani Bhattacharjee, Abhijit Bandyopadhyay, Sovan Chakraborty +3
It has been known that neutrinos from supernova (SN) bursts can give rise to nuclear recoil (NR) signals arising from coherent elastic neutrino-nucleus scattering (CENS) interac…
Probing low-mass WIMP candidates of dark matter with tetrafluoroethane superheated liquid detectors
Susnata Seth, Sunita Sahoo, Pijushpani Bhattacharjee +1
Probing low mass (sub-GeV -- few GeV) Weakly Interacting Massive Particle (WIMP) candidates of dark matter through WIMP-induced nuclear recoils in direct detection experiments requ…
Baryogenesis via Leptogenesis in presence of cosmic strings
Narendra Sahu, Pijushpani Bhattacharjee, Urjit A Yajnik
We study the effect on leptogenesis due to cosmic strings of a extension of the Standard Model. The disappearance of closed loops of cosmic strings can pro…
Probing neutrino mixing angles with ultrahigh energy neutrino telescopes
Pijushpani Bhattacharjee, Nayantara Gupta
We point out that detecting $\nuebar$'s from distant astrophysical sources with the up-coming and future neutrino telescopes using the Glashow resonance channel $\nuebar e^{-}\to W…
B-L Cosmic strings and Baryogenesis
Pijushpani Bhattacharjee, Narendra Sahu, U. A. Yajnik
Cosmic strings arising from breaking of the gauge symmetry that occurs in a wide variety of unified models can carry zero modes of heavy Majorana neutrinos. Decaying a…
