=  '''Collider Phenomenology''' (Oxford, BUSSTEP 2018)=

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

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:

== 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
