Abstract

In analyzing neutrino oscillation experiments it is often assumed that while new physics contributes to neutrino masses, neutrino interactions are given by the Standard Model. We develop a formalism to study new physics effects in neutrino interactions using oscillation experiments. We argue that the notion of branching ratio is not appropriate in this case. We show that a neutrino appearance experiment with sensitivity to oscillation probability PijexpP_{ij}^{exp} can detect new physics in neutrino interactions if its strength GNG_N satisfies (GN/GF)2Pijexp(G_N/G_F)^2 \sim P_{ij}^{exp}. Using our formalism we show how current experiments on neutrino oscillation give bounds on the new interactions in various new physics scenarios.
