Large short-baseline (v)over-barμ disappearance

We analyze the LSND, KARMEN, and MiniBooNE data on short-baseline (nu) over bar (mu) -> (nu) over bar (e) oscillations and the data on short-baseline (nu) over bar (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) over bar (mu) disappearance and the KamLAND observation of very-long-baseline (nu) over bar (e) disappearance. We show that the fit of the data implies that the short-baseline disappearance of (nu) over bar (mu) is relatively large. We obtain a prediction of an effective amplitude sin(2)2v(mu mu) greater than or similar to 0.1 for short-baseline (nu) over bar (mu) disappearance generated by 0.2 less than or similar to Delta m(2) less than or similar to 1 eV(2), which could be measured in future experiments.
