The partial widths are determined for stop decays to top quarks and gluinos, and gluino decays to stop particles and top quarks (depending on the masses of the particles involved). The widths are calculated including one-loop SUSYQCD corrections. The radiative corrections for these strong-interaction decays are compared with the SUSY-QCD corrections for electroweak stop decays to quarks and neu...

We present recent results on the first moments of parton distributions using gauge configurations generated with two degenerate flavors of light twisted mass quarks with pion mass fixed approximately to its physical value. We also present a first study of the vector parton distribution function using a twisted mass ensemble at pion mass of 373 MeV.

The evaluation of the NNLO QCD corrections to the production of a scalar and a pseudo-scalar Higgs boson is described. The evaluation of the NNLO QCD corrections to the production of a scalar and a pseudo-scalar Higgs boson is described.

I present a short overview of the NLO QCD calculations available for deep-inelastic production of heavy quarks.

We present a review of measurements of α S. The individual measurements are discussed and intermediate averages for classes of related measurements are found. The final average is built using the intermediate values. Correlations are treated consistently. The ICHEP 2006 world average is α S (m Z 0) = 0.1175 ± 0.0011 dominated by the recent result from lattice QCD.

In the last few years, lattice QCD has made a dramatic progress in understanding the physics of hadrons containing heavy quarks, from the first principle. This review summarises the major achievements.
