Abstract

We investigate the signature of a heavy charged Higgs boson of the minimal super-symmetric standard model in the lepton plus multijet channel at the CERN Large Hadron Collider with four b tags. The signal is the gluon-gluon fusion process g → g t ¯ b H − , followed by the H − → ¯ t b decay, while the main background is from g → g t ¯ t b ¯ b . We find that 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 ε b ∼ 5 0 % , this channel can provide a viable signature over a limited but interesting range of the parameter space.
