Title: Large short-baseline {nu}{sub {mu}} disappearance

Abstract

We analyze the LSND, KARMEN, and MiniBooNE data on short-baseline {nu}{sub {mu}{yields}{nu}e} oscillations and the data on short-baseline {nu}{sub e} disappearance obtained in the Bugey-3 and CHOOZ reactor experiments in the framework of 3+1 antineutrino mixing, taking into account the MINOS observation of long-baseline {nu}{sub {mu}} disappearance and the KamLAND observation of very-long-baseline {nu}{sub e} disappearance. We show that the fit of the data implies that the short-baseline disappearance of {nu}{sub {mu}} is relatively large. We obtain a prediction of an effective amplitude sin{sup 2}2{theta}{sub {mu}{mu}} > or approx. 0.1 for short-baseline {nu}{sub {mu}} disappearance generated by 0.2 < or approx. {Delta}m{sup 2} < or approx. 1 eV{sup 2}, which could be measured in future experiments.
