Abstract

Abstract We propose to exploit the anisotropy of the positrons emitted in the reaction v e + p → n + e + for extracting a possible antineutrino signal from the Superkamiokande background. The sensitivity to v e → v e transition probability is at the 3% level already with the statistics collected in the first hundred days. Within three years of data taking, this sensitivity will reach the 1% level, thus providing a stringent test of several theoretical models.
