We discuss our present knowledge of α s, the fundamental running coupling or effective
charge of Quantum Chromodynamics (QCD). A precise understanding of the running of α s …

We review the present theoretical and empirical knowledge for α s, the fundamental
coupling underlying the interactions of quarks and gluons in Quantum Chromodynamics …

We calculate the unpolarized and polarized three–loop anomalous dimensions and splitting
functions P NS+, P NS− and P NS s in QCD in the MS‾ scheme by using the traditional …

A bstract We calculate the massless unpolarized Wilson coefficients for deeply inelastic
scattering for the structure functions F 2 (x, Q 2), FL (x, Q 2), xF 3 (x, Q 2) in the\(\overline …

The second part of this review is devoted to the Higgs sector of the Minimal Supersymmetric
Standard Model. The properties of the neutral and charged Higgs bosons of the extended …

We compute the next-to-next-to-leading order (NNLO) contributions to the three splitting
functions governing the evolution of unpolarized non-singlet combinations of quark densities …

We implement, at next-to-next-to-leading order, the QCD corrections to Standard Model
Higgs boson production in association with vector bosons at hadron colliders, qq ̄→ HV …

We present the next-to-next-to-leading order (NNLO) corrections to the total cross section for
(pseudo-) scalar Higgs boson production using an alternative method than those used in …

The total cross section for Higgs boson production in bottom-quark annihilation is evaluated
at next-to-next-to-leading order in QCD. This is the first time that all terms at order α s 2 are …

We have computed the four lowest even-N moments of all four splitting functions for the
evolution of flavour-singlet parton densities of hadrons at the fourth order in the strong …
