Abstract
Although the Standard Model has been confirmed to stunning precision, at each new collider it is further scrutinized to ever-increasing precision. Measurements of Standard Model processes are an essential part of the physics program at the Tevatron and LHC proton colliders. Apart from challenging the theory in new energy regimes and phase spaces, they provide the means to search for extensions of the Standard Model and give confidence in the tools used for new physics searches. Indeed, deviations from Standard Model predictions may be the first indications for physics beyond the Standard Model. In these lectures, the experimental methods used at the LHC and Tevatron will be discussed and results presented on QCD and electroweak processes, as well as on the study of properties of the top quark.

They also inform the interaction between particle and astro-particle physics.
- 2.
Recently the cross section has been determined in full NNLO QCD corrections with NNLL soft gluon summation [58]. They obtain an improved precision of 172\(_{-7.5}^{+6}\) pb, and 245.8\(_{-10.6}^{+8.8}\) pb respectively.
- 3.
Measurements support this hypothesis.
- 4.
A complementary method has recently been suggested [74].
- 5.
In principle also quarks can be used. As long as a fermion from the W decay can be distinguished from its anti-fermion, the W boson helicity can be measured. This is very challenging and only possible for a few quark species. Methods exist to identify e.g. the charge of a charm quark jet; however, these are rather inefficient.

Acknowledgements
I would like to thank the organisers of the Scottish Universites Summer School on Physics, especially Craig Buttar and Franz Muheim, for inviting me to this exciting school. It was a real pleasure to have the many discussions with so many high quality students. I very much enjoyed also for being introduced to Scottish history, landscape and spirits.
