After more than 25 years of considerable theoretical and experimental efforts, it appears that QCD is the theory of strong interactions. Ideally, in high-energy QCD one needs one single piece of information from the experiments: the value of αs. Starting from that measured value, every observable can be computed from first principles. In practice this is not feasible, since we don’t know how to...

We present the next-to-leading order QCD corrected total cross sections and the distributions of the transverse momenta of the final anti-bottom-quark, top-quark and charged Higgs-boson for the processes of pp̄/pp → tb̄H− + X in the minimal supersymmetric standard model(MSSM) at the Tevatron and the LHC. We find that the NLO QCD corrections significantly modify the leading-order distributions of ...
