Detection of left-handed sneutrinos at the LHC via displaced vertices

The μνSSM is a supersymmetric R-parity breaking model with the minimal natural matter content. The model has desirable properties as absent of mu-problem and the ability to reproduce neutrino physics experiments. In this context, we analyse relevant signals expected at the LHC for a left sneutrino as the lightest supersymmetric particle (LSP). In particular we analyse a displaced dilepton signal expected at the LHC for a tau left sneutrino as the lightest supersymmetric particle with a mass in the range 45-100 GeV.
