QCD and Collider Physics (Florence, GGI 2017)
10h course on QCD, MC's and 8h tutorials on QCD and the physics of colliders, in particular the LHC, by Fabio Maltoni and Marco Zaro
An introduction to the phenomenology of strong interactions at high-energy colliders is given. We focus on the basic concepts and results in perturbative QCD that allow us not only to describe but also reliably predict rates and features of SM (as well as of New Physics) events at the LHC.
- The parton model: from DIS to hadron-hadron collider phenomenology.
- Perturbative QCD as a weakly interacting theory of gluons and quarks at high-energy.
- The IR structure of QCD in e+e- collisions: infrared safety, parton showers and jets.
- Factorisation, DGLAP evolution, accurate and precise QCD predictions for LHC physics.
- Selected topics in New Physics searches and SM measurements the LHC.
The course includes tests, simple exercises, fully worked out numerical calculations/simulations, and a complete and easy-to-use series of mathematica notebooks which support the computation at next-to-leading order accuracy of the total production cross section of a Higgs boson in gluon-gluon fusion at the
Lectures (F. Maltoni)
Lectures are given on the blackboard.

Slide summary of the lectures
Tutorials (M. Zaro)
8h of tutorials on QCD and aspects of computations in QCD, spanning from LO to NLO calculations with applications using MadGraph5_aMC@NLO.
We provide here complementary material to the lectures that can used by students to verify their understanding of the basic concepts.
