Gaugino pair production at LHC for the case of nonuniversal gaugino masses

We investigate \chi^{+/-}_1 \chi^0_2 pair production at LHC (CMS) with subsequent decays into leptons for the case of nonuniversal gaugino masses. Visibility of signal by an excess over SM background in 3 leptons + no jet + E^{miss}_T events depends rather strongly on the relation between LSP mass \chi^0_1 and \chi^{+/-}_1 mass. We also give some preliminary results on the investigation of squark and gluino production at LHC for the case of nonuniversal gaugino masses.
