Abstract
We calculate the dipole amplitude for the decay and
related processes
in the left-right supersymmetric model when parity breaking occurs at
a considerably large scale.
The low-energy flavor violation in the model originates either from the
nonvanishing
remnants of the left-right symmetry in the slepton mass matrix or from the
direct flavor changing lepton-slepton-neutralino interaction. The result is
found to be large and already accessible with current experimental accuracy
for supersymmetric masses not far above the electroweak scale.
It also provides nontrivial constraints on the lepton mixing in the
model.
