Signatures for the Charged Higgs Decay of the Top Quark at the Tevatron
  We investigate the effect that a charged Higgs decay channel for the top quark has on the signature for top quark pair production at the Tevatron. The branching ratios for the various multijet and multilepton final states arising from top pair production are obtained for a wide range of values for tangent beta and the charged Higgs boson mass. In addition, the effect of the charged Higgs decay of the top quark on the 2 b-tagged jets and 1 lepton channel is considered.
