Non-universal scalar mass scenario with Higgs funnel region of SUSY dark matter: a signal-based analysis for the Large Hadron Collider

摘要

We perform a multilepton channel analysis in the context of the Large HadronCollider (LHC) for Wilkinson Microwave Anisotropy Probe (WMAP) compatiblepoints in a model with non-universal scalar masses, which admits a Higgs funnelregion of supersymmetry dark matter even for a small $\tan\beta$. In additionto two and three-lepton final states, four-lepton events, too, are shown to beuseful for this purpose. We also compare the collider signatures in similarchannels for WMAP compatible points in the minimal supergravity (mSUGRA)framework with similar gluino masses. Some definite features of suchnon-universal scenario emerge from the analysis.
