  One of the main motivations of experiments at the LHC is to search for SUSY
particles. The talk is based on recent analyses, performed by CMS
Collaboration, within the framework of the Supergravity motivated minimal SUSY
extension of the Standard Model. The emphasis is put on leptonic channels. The
strategies for obtaining experimental signatures for strongly and weakly
interacting sparticles productions, as well as examples of determination of
SUSY masses and model parameters are discussed. The domain of parameter space
where SUSY can be discovered is investigated. Results show, that if SUSY is of
relevance at Electro-Weak scale it could hardly escape detection at LHC.
