Comment on "Gravitationally Induced Neutrino-Oscillation Phases"
Tanmoy Bhattacharya, Salman Habib, Emil Mottola
Abstract
We critically examine the recent claim (gr-qc/9603008) of a ``new effect'' 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 relativistic effect of the star's gravity on neutrino oscillations, it is not of the form claimed, and is too small to be measured.
