The search for charge sleptons and flavour lepton number violation at LHC (CMS)

We study a possibility to detect charged sleptons and flavour lepton number violation at LHC (CMS). We investigate the production and decays of right- and left-handed sleptons separately. We have found that for luminosity L = 105pb 1 it would be possible to detect right- handed sleptons with a mass up to 325 GeV and left-handed ones with a mass up to 350 GeV. We also investigate a possibility to look for flavour lepton number violation in slepton decays due to the mixing of different sleptons generations. We find that for maximal (˜µR − ˜ eR) mixing sleptons detection is possible up to masses of about 250 GeV.
