I review the current status of lattice calculations of heavy quark quantities. Particular emphasis is placed on leptonic and semileptonic decay matrix elements.
We report on our results about hadronic tt̄ production at NLO QCD including t, t̄ spin effects, especially on tt̄ spin correlations.
We review the status of an ongoing long-term lattice investigation of the spectrum and structure of tetraquark candidates. We focus on the light scalar meson a0(980). First steps regarding the study of a possibly existing ccc̄c̄ tetraquark are also outlined.
We discuss W boson production at HERA including NLO QCD corrections. A detailed comparison with previous work is presented.
Supersymmetry predicts that gauge couplings are equal to the corresponding gauginosfermion-fermion Yukawa couplings. This prediction can be tested for the QCD sector of the MSSM by studying the processes e+e− → squark+antisquark+gluon and e+e− → squark+antiquark+gluino at a future linear collider. We present results for these processes at next-to-leading order in αs in the framework of the MSSM...
