Abstract:
Supersymmetric models with bi-linear R-parity violation (BRpV) account
for the observed neutrino masses and mixing parameters and leads
lightest supersymmetric particle (LSP) unstable. The LSP properties,
such as mass, lifetime and branching ratios, are related to neutrino
properties. In Left-Right (LR) symmetrical extensions of the Standard
Model (SM) heavy right-handed neutrinos appear with masses of the
order of TeV. The decays of such heavy neutrinos leads to lepton
flavor violating signature. In some extension of minimal
supersymmetric version of the SM (MSSM),such as CP-violation or adding
an extra singlet,  the Higgs bosons could be lighter. This might be
one of reason the Higgses are yet undetected at collider experiments.
We address these issues and the ways to find their signatures at Large
Hadron Collider.
