Query: Top quark and charged Higgs at the Tevatron-Run II   We shortly review the top quark decay into charged Higgs, and present new
results on its production at the upgraded Tevatron. We have computed the MSSM
cross-section for single charged Higgs in association with the top quark beyond
the regime of on-shell t t-bar production followed by the decay t -> H+ b. Our
results are higher than recent results in the literature. In the case where H+
belongs to the Higgs sector of the MSSM, we show that the leading
supersymmetric radiative corrections may substantially increase the
cross-section. Overall we find that the charged Higgs production process can be
complementary to the neutral Higgs production processes W\Phi and b b-bar\Phi,
which have been studied under similar circumstances. Since the neutral and
charged Higgs channels are enhanced in the same region of the parameter space,
the simultaneous detection of all these processes could be essential for an
effective experimental underpinning of the nature of these Higgs particles at
the Tevatron-Run II.
