Title Detecting Heavy Charged Higgs Bosons at the LHC with Four b- Quark Tags
Abstract We investigate the signature of a heavy charged Higgs boson of the Minimal Supersymmetric Standard Model in the lepton plus multi-jet channel at the Large Hadron Collider with four b-tags. The signal is the gluon-gluon fusion process gg ->. tb(bar)H(superscript)-, followed by the H(superscript)- ->. t(bar)b decay, while the main background is from gg ->. tt(bar)bb(bar). We find that the the two can be separated effectively by kinematic cuts and mass reconstruction, but the signal size is not very large in the end. Nonetheless, with a good b-tagging efficiency, e(subscript)b ~ 50%, this channel can provide a viable signature over a limited but interesting range of the parameter space.
