Reply to the comment on "Topological phase in two flavor neutrino oscillations"

Abstract

In a recent paper [arXiv:0901.0790], we showed that there is a neat geometric interpretation of two flavor neutrino oscillation formulae, and that the geometric phase involved in the physics of oscillations is restricted to be topological as long as CP is conserved. This paper has been criticised by Bhandari [arXiv:1006.5935]. In the present note, we show that the criticisms are not valid and only reflect his failure to understand some crucial points.
