Probing a mixed neutralino dark matter model at the 7 TeV LHC
Probing a mixed neutralino dark matter model at the 7 TeV LHC
We have analyzed the prospect of probing a nonuniversal gaugino mass model of mixed bino-Higgsino dark matter at the current 7 TeV run of LHC. It provides cosmologically compatible dark matter relic density over two broad bands of parameters, corresponding to ${m}_{\stackrel{\texttildelow{}}{g}}<{m}_{\stackrel{\texttildelow{}}{q}}$ and ${m}_{\stackrel{\texttildelow{}}{g}}\ensuremath{\sim}{m}_{\stackrel{\texttildelow{}}{q}}$. The supersymmetry spectrum of this model …
