This article reports the status of a νμ→νe oscillation
search in MiniBooNE (Booster Neutrino Experiment) experiment. If an appearance
signal is observed, it will imply Physics Beyond the Standard Model such as the
existence of light sterile neutrino.Comment: 6 pages, 4 figures. Plenary talk at the Neutrino Oscillation Workshop
(NOW2006), September 2006, to be published in Nucl.Phys. B (Proc. Suppl.
