摘要：

We recently proposed that, due to the top-quark-mass enhanced Yukawa coupling, the s-channel production of a charged scalar or pseudoscalar from heavy quark fusion can be an important new mechanism for discovering nonstandard spin-0 particles. In this work, we present the complete O(alpha(s)) QCD corrections to this s-channel production process at hadron colliders, and also the results of QCD resummation over multiple soft-gluon emission. The systematic QCD-improved production and decay rates at the Fermilab Tevatron and the CERN LHC are given for the charged top pions in the top-color models, and for the charged Higgs bosons in the generic two Higgs doublet model. The direct extension to the production of the neutral (pseudo)scalars via bg fusion is studied in the minimal supersymmetric standard model (MSSM) with large tan beta, and in the top-color model with a large bottom Yukawa coupling.
