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 χ^0_1 and χ^{+/-}_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.1 latex files (10 pages)High Energy Physics - Phenomenologytext
