Search for SUSY at LHC in Jets + $E^{miss}_{T}$ final states for the case of nonuniversal gaugino masses

We investigate squark and gluino pair production at LHC (CMS) with subsequent decays into quarks and LSP for the case of nonuniversal gaugino masses. Visibility of signal by an excess over SM background in (n > 1)jets + E^{miss}_T events depends rather strongly on the relation between LSP, gluino...

description We investigate squark and gluino pair production at LHC (CMS) with subsequent decays into quarks and LSP for the case of nonuniversal gaugino masses. Visibility of signal by an excess over SM background in (n > 1)jets + E^{miss}_T events depends rather strongly on the relation between LSP, gluino and squark masses and it decreases with the increase of LSP mass. For relatively heavy LSP mass closed to squark or gluino masses and for (m_{\tilde{q}}, m_{\tilde{g}}) > 1.5 TeV signal is too small to be observable. For the case when only third generation squarks and LSP are relatively light signal is not visible without b-tagging.
