摘要：

We investigate squark and gluino pair production at LHC (CMS) with subsequent decays into quarks and an LSP for the case of nonuniversal gaugino masses. Visibility of a signal by an excess over the SM background in (n greater than or equal to 2)jets + E-T(miss) events depends rather strongly on the relation between the LSP, gluino, and squark masses and decreases with increasing LSP mass. For a relatively heavy LSP mass close to the squark or the gluino mass and for m((q) over bar), m((g) over bar) greater than or equal to 1.5 TeV, the sygnal is overly small to be observable.
