Gravitationally Induced Neutrino - Oscillation Phases " Tanmoy Bhattacharya

We critically examine the recent claim of a \new eeect" of gravitationally induced quantum mechanical phases in neutrino oscillations. A straightforward exercise in the Schwarzschild coordinates appropriate to a spherically symmetric non-rotating star shows that, although there is a general relativis-tic eeect of the star's gravity on neutrino oscillations, it is not of the form claimed, and is too small to be measured.
