Query: Neutrino radiative decay and lepton flavor violation in supersymme tric
  models   The radiative decay of neutrino,such as (\bar{\nu_{\tau}}: \longrightarrow:
\nu_{\mu}+\gamma), in the minimal supersymmetric standard model with
right-handed neutrinos (MSSMRN) and in the (SU(5)) grand unified theory with
right-handed neutrinos((SU(5)RN))model is examined.In these models,the
transition magnetic moment of neutrino is directly proportional to the neutrino
mass.For different values on SUSY parameters (compatible with the relic
density) and for large mixing angle solution to the atmospheric neutrino
problem,the transition magnetic moment can be a few times greater than,or
comparable to,the value of the standard model (with a right-handed neutrino
singlet added).
