Query: Revisiting lepton flavor violation in supersymmetric type II seesaw   In view of the recent measurement of reactor mixing angle $\theta_{13}$ and
updated limit on $BR(\mu \to e \gamma)$ by the MEG experiment, we re-examine
the charged lepton flavor violations in a framework of supersymmetric type II
seesaw mechanism. Supersymmetric type II seesaw predicts strong correlation
between $BR(\mu \to e \gamma)$ and $BR(\tau \to \mu \gamma)$ mainly in terms of
the neutrino mixing angles. We show that such a correlation can be determined
accurately after the measurement of $\theta_{13}$. We compute different factors
which can affect this correlation and show that the mSUGRA-like scenarios, in
which slepton masses are taken to be universal at the high scale, predicts $3.5
\lesssim BR(\tau \to \mu \gamma)/BR(\mu \to e \gamma) \lesssim 30$ for normal
hierarchical neutrino masses. Any experimental indication of deviation from
this prediction would rule out the minimal models of supersymmetric type II
seesaw. We show that the current MEG limit puts severe constraints on the light
sparticle spectrum in mSUGRA model if the seesaw scale lies within
$10^{13}$-$10^{15}$ GeV. It is shown that these constraints can be relaxed and
relatively light sparticle spectrum can be obtained in a class of models in
which the soft mass of triplet scalar is taken to be non-universal at the high
scale.
