=  '''Collider Physics: advanced topics''' (Bologna, PhD course 2020, 12h)=

An introduction to collider physics, starting with QCD and then moving to Higgs-boson and top-quark phenomenology.  

Slides of the Glasgow school in 2019, focusing on top physics:

1. Week One: QCD for Colliders    [https://www.dropbox.com/s/relhz216tr0ekke/Week1-QCD.pdf?dl=0 Slides]
1. Week Two: Going Beyond the SM  [https://www.dropbox.com/s/ydd27i69fhno0x9/Week2-SM.pdf?dl=0 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
