W boson production at the LHC

In this talk I will discuss the charged-current Drell-Yan (DY) process, i.e. single W-boson production with leptonic decay in hadron collisions, and its role in the Standard Model precision tests as well as searches for the Higgs boson and for "new physics". I will show important differences between the Tevatron and the LHC with respect to DY processes and discuss their consequences for the W mass measurement. Finally, I will briefly present the Monte Carlo event generator WINHAC, dedicated to precision predictions for the above processes at the LHC.

Understanding the proton's spin structure

After more than 20 years of measurements of the spin-dependent structure functions of the nucleon the third generation of precise polarized experiments is now running and new data are analyzed. Although our knowledge about the spin decomposition in the frame of quark parton model and QCD is now more complete and the polarized parton distribution functions are better constrained by data, the driving question for QCD spin physics still has no answer: where does the nucleon spin come from? I will try to present a modern understanding of the problem and a possible explanation in the light of new experimental data and new results obtained in lattice QCD.

Supersymmetric mass spectra for gravitino dark matter with a high reheating temperature

Supersymmetric theories with gravitino dark matter generally do not allow the high reheating temperature required by thermal leptogenesis without running afoul of relic abundance or big bang nucleosynthesis constraints. We discuss new examples of particular supersymmetric mass spectra that do satisfy these requirements. The main implication is the near degeneracy of the gluino with the other neutralinos in the spectrum.
