Collider Phenomenology (Oxford, BUSSTEP 2017)

An introduction to the collider physics, through a quick tour on perturbative QCD (with the minimum required to understand LHC events) and examples of phenomenology of jets, Higgs and the top quark.

Lectures are given at the blackboard with some material presented through slides. Reference slides containing a much wider selection of topics with respect to those actually presented can be found here:

1. A QCD tool box Slides

2. The SM of EW interactions Slides

3. The Higgs boson Slides

4. The Top quark Slides

5. Searching New Physics through the Higgs and the top quark Slides

Supporting material

The course includes tests, simple exercises, fully worked out numerical calculations/simulations, and a complete and easy-to-use series of mathematica notebooks which allow the computation at next-to-leading order accuracy of the total production cross section of a Higgs boson in gluon-gluon fusion at the LHC
