=  '''Collider Phenomenology''' (Oxford, BUSSTEPP 2018/Glasgow, BUSSTEPP 2019)=

An introduction to collider physics, with examples on Higgs-boson and top-quark phenomenology.

== 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



===== Tests and exercises =====
