Title: Confronting mass-varying neutrinos with MiniBooNE

Abstract

We study the proposal that mass-varying neutrinos could provide an explanation for the LSND signal for {nu}{sub {mu}}{yields}{nu}{sub e} oscillations. We first point out that all positive oscillation signals occur in matter and that three active mass-varying neutrinos are insufficient to describe all existing neutrino data including LSND. We then examine the possibility that a model with four mass-varying neutrinos (three active and one sterile) can explain the LSND effect and remain consistent with all other neutrino data. We find that such models with a 3+1 mass structure in the neutrino sector may explain the LSND data and a null MiniBooNE result for 0.10 < or approx. sin{sup 2}2{theta}{sub x} < or approx. 0.30. Predictions of the model include a null result at Double-CHOOZ, but positive signals for underground reactor experiments and for {nu}{sub {mu}}{yields}{nu}{sub e} oscillations in long-baseline experiments.
