Deviation from Bimaximality due to Planck scale effects
Bipin Singh Koranga, Mohan Narayan, S. Uma Sankar
We consider the effect of Planck scale operators on neutrino mixing. We assume that GUT scale operators give rise to degenerate neutrino masses with bimaximal mixing. Quantum gravi…
Possible CPT Violation from Planck Scale Effects
Bipin Singh koranga, Mohan Narayan, S Uma Sankar
At present there is good agreement between the neutrino mass-squared difference determined from the solar neutrino data and the anti-neutrino mass-squared difference determined fro…
Small eta-N scattering lengths favour eta-d and eta-alpha states
N. G. Kelkar, K. P. Khemchandani, B. K. Jain
Unstable states of the eta meson and the 3He nucleus predicted using the time delay method were found to be in agreement with a recent claim of eta-mesic 3He states made by the TAP…
Possible eta-mesic 3He states within the finite rank approximation
N. G. Kelkar, K. P. Khemchandani, B. K. Jain
We extend the method of time delay proposed by Eisenbud and Wigner, to search for unstable states formed by eta mesons and the 3He nucleus. Using few body equations to describe eta…
