[en] We perform a multilepton channel analysis in the context of the Large Hadron Collider (LHC) for Wilkinson Microwave Anisotropy Probe compatible points in a model with nonuniversal scalar masses, which admits a Higgs funnel region of supersymmetry dark matter even for a small tanβ. In addition to two- and three-lepton final states, four-lepton events, too, are shown to be useful for this purpose. We also compare the collider signatures in similar channels for Wilkinson Microwave Anisotropy Probe compatible points in the minimal supergravity (mSUGRA) framework with similar gluino masses. Some definite features of such nonuniversal scenario emerge from the analysis.
