We examine the possibility of finding charged Higgs bosons (H±) at the SSC. The charged Higgs boson is produced with a top quark via a gluon+bottom quark interaction (g+b→H+t). For the two Higgs doublet models, H± decays predominantly into t+b. Since the background from QCD processes will be very severe for this decay mode, we studied the H±→τ+ν decay mode. Even for this mode, background from the processes pp→W+t+spectators→ℓ+νℓ+t+spectators will be very high. In the two Higgs doublet models, it is very difficult to extract the charged Higgs signal for reasonable values of the ratio of the two vacuum expectation values ( tan β=v1/v2).
