Title: Signature of neutrinos and Higgses at Large Hadron Collider

Speaker: Dr. Siba Prasad Das, Dept. of Physics, Viswa Bharati University, Santiniketan (WB)

Abstract: Supersymmetric models with bilinear 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 the reasons the Higgses are yet undetected at collider experiments. We address these issues and the ways to find their signatures at Large Hadron Collider.
