Abstract

We analyze the LSND, KARMEN, and MiniBooNE data on short-baseline \ensuremathν_\ensuremathμ\ensuremath→\ensuremathν_e oscillations and the data on short-baseline \ensuremathν_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 \ensuremathν_\ensuremathμ disappearance and the KamLAND observation of very-long-baseline \ensuremathν_e disappearance. We show that the fit of the data implies that the short-baseline disappearance of \ensuremathν_\ensuremathμ is relatively large. We obtain a prediction of an effective amplitude sin²2\ensuremathϑ_\ensuremathμ\ensuremathμ\ensuremath\gtrsim0.1 for short-baseline \ensuremathν_\ensuremathμ disappearance generated by 0.2\ensuremath\lesssim\ensuremathΔm²\ensuremath\lesssim1 eV², which could be measured in future experiments.
