Abstract

The result of a search for the neutrino oscillation mode ν¯μ→ν¯e in a fine-grained tracking detector is reported. The average neutrino energy is 40 MeV and the average detector distance from the neutrino source is 26.8 m. No evidence for neutrino oscillations through this mode is observed. Limits on δm2 and sin2(2θ) are presented.
