A way to limit selectron mass using supernova neutrino data

  • P. Ram Babu
  • T. Chhabra


A way to estimate photino contamination in neutrino flux from supernova is suggested. By comparing the experimental and theoretically expected ratios of forward-peaked events in the direction of neutrino source and isotropic events one can set a limit on selectron mass. As an example the data from SN 1987A have been used to set a limit on selectron mass.
