摘要：

We discuss the viability of gb --> tH --> ttb charged-Higgs signals at the proposed LHC pp supercollider, in the decay channel tt --> (bqqBAR') (blnu). Here one top quark decays hadronically and one semileptonically, with all three b-quarks giving flavor-tagged jets. The principal backgrounds come from ttg, ttq, ttc and ttb continuum production, with possible mis-tagging of g, q and c. We conclude that significant signals can be separated from these backgrounds, for limited but interesting ranges of the parameters M(H+/-) and tan beta, with the LHC energy and luminosity.
