Probing the light Higgs pole resonance annihilation of dark matter in the light of XENON100 and CDMS-II observations

We consider the prospect of lightest neutralino (${\stackrel{\texttildelow{}}{\ensuremath{\chi}}}_{1}^{0}$) as a dark matter candidate in light of recent interesting observations from the XENON100 and CDMS-II experiments in minimal supergravity framework with large $\mathrm{tan}\ensuremath{\beta}$ and nonvanishing ${A}_{0}$. Within the WMAP satisfied zone, there is a large direct detection reach of lighter ${\stackrel{\texttildelow{}}{\ensuremath{\chi}}}_{1}^{0}$ in the lighter Higgs boson mediated resonance annihilation domain of the above scenario. It is seen that the heavier Higgs boson plays a dominating role in the ${\stackrel{\texttildelow{}}{\ensuremath{\chi}}}_{1}^{0}\ensuremath{-}p$ cross section in the associated zone of parameter space in spite of having a larger mass. Possible LHC signatures are discussed.
