Title: Neutrino Oscillations, Shortcuts in Extra Dimensions and LSND

Abstract: After summarising the current status of the possible explanations for the LSND observations, I describe one in particular in some detail. This is one in which the sterile neutrino mixing with the flavor ones propagates in the bulk (extra dimension) and travels at a different effective speed than the active one. This gives rise to a new resonance which allows an explanation of the LSND effect, and at the same time satisfies all constraints from various null results such as Bugey and CDHS, avoids the problems with atmospheric and solar data which plague the conventional sterile mixing scenarios, and makes striking predictions for several experiments, especially Mini-Boone and a stopped pion source at SNS.
