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\stackrel\ensuremath→gtbH^\ensuremath-, followed by the H^\ensuremath-\ensuremath→tb decay, while the main background is from g\stackrel\ensuremath→gttbb. 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 \ensuremathεb\ensuremath∼50%, this channel can provide a viable signature over a limited but interesting range of the parameter space.
