Neutrinos from Supernovae
Sandhya Choubey, Kamales Kar
In this review, the effect of flavor oscillations on the neutrinos released during supernova explosion after core collapse is described. In some scenarios there are large enhanceme…
The Solar Neutrino Problem after the first results from Kamland
Abhijit Bandyopadhyay, Sandhya Choubey, Raj Gandhi +2
The first results from the KamLAND experiment have provided confirmational evidence for the Large Mixing Angle (LMA) MSW solution to the solar neutrino problem. We do a global anal…
SNO and the solar neutrino problem
Sandhya Choubey, Abhijit Bandyopadhyay, Srubabati Goswami +1
We study the implication of the first neutral current (NC) data from SNO. We perform model independent and model dependent analyses of the solar neutrino data. The inclusion of the…
Gamma ray bursts as probes of neutrino mass, quantum gravity and dark energy
Sandhya Choubey, S. F. King
We calculate the time delays of neutrinos emitted in gamma ray bursts due to the effects of neutrino mass and quantum gravity using a time dependent Hubble constant which can signi…
A minimal three generation seesaw scenario for LSND
Biswajoy Brahmachari, Sandhya Choubey, Rabindra N. Mohapatra
We show that in the minimal three generation seesaw models for neutrinos, the presence of leptonic symmetry leads to one of the right handed neutrinos rem…
Implications of the first neutral current data from SNO for Solar Neutrino Oscillation
Abhijit Bandyopadhyay, Sandhya Choubey, Srubabati Goswami +1
We perform model independent and model dependent analyses of solar neutrino data including the neutral current event rate from SNO. The inclusion of the first SNO NC data in the mo…
