  We study a possibility to detect sleptons at post-WMAP benchmark points at
LHC(CMS). We find that at $L_{tot}=30 fb^{-1}$ it would be possible to detect
sleptons at points A, B, C, D, G. We also investigate the production and decays
of right and left sleptons separately. We find that at $L_{tot}=30 fb^{-1}$ it
would be possible to detect right sleptons with a mass up to 200 GeV and left
ones with a mass up to 300 GeV.
