Abstract

The sneutrino is a viable NLSP candidate in SUSY with gravitino LSP. In my talk I will focus on this possibility, in particular concentrating on the question of whether the LHC can distinguish spectra with a sneutrino NLSP from alternatives, e.g. ones with neutralino LSP. I will show that there are at least two different families of experimentally allowed spectra with sneutrino NLSP which exhibit distinctive multilepton signals. These spectra are not easy to fake within the MSSM. I will discuss these signals in detail and illustrate our analysis approach on simulations.
