=  '''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  [attachment:BUSSTEP-QCD.pdf Slides]

2. The SM of EW interactions [attachment:BUSSTEP-SM.pdf Slides]

3. The Higgs boson [attachment:BUSSTEP-Higgs.pdf Slides]

4. The Top quark [attachment:BUSSTEP-Top.pdf Slides]

5. Searching New Physics through the Higgs and the top quark [attachment:BUSSTEP-NewPhysicsHiggsTop.pdf 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

We provide here complementary material to the lectures that can used by students to verify their understanding of the basic concepts.
