LHC SUSY Search Gluino and squark masses around 1.7 Tev in the cmssm and msugra Gluino mass low bound is around 1. 3 tev Stop/ sbottom mass low bounds are around 600 GeV If the lsp is heavy, all the bounds can be relaxed
LHC SUSY Search • Gluino and squark masses around 1.7 TeV in the CMSSM and mSUGRA. • Gluino mass low bound is around 1.3 TeV. • Stop/sbottom mass low bounds are around 600 GeV. • If the LSP is heavy, all the bounds can be relaxed
show that if LSP mass is greater than w 500 GeV, any gluino heavier than this mass can because of the smaller production rate. The bounds become a little strong for g+ttY and 9+bbX which are the favoured decay chain in nat ural SUSY. In this case, the gluino can evade all LHC search when mLsP 700 GeV. And the value drops to w 600 GeV for gluino with mass larger than w 1100 GeV. Note that the corresponding bounds can be loosen in
