 == Preparatory Material ==

The school is meant to introduce to young researchers in phenomenology and experimental LHC physics the MC tools necessary
to perform accurate simulations and analyses. Particular emphasis will be given to NLO calculations, their interface to the shower programs, and  applications to jet physics. While the basics will be reviewed during the lectures, the school assume basic knowledge of
perturbative QCD concepts and methods.

We invite the students to study the excellent introductory lectures:[[BR]]
	
Elements of QCD for hadron colliders.[[BR]]
Gavin P. Salam (CERN)[[BR]]
e-Print: arXiv:1011.5131 [hep-ph] [[BR]]

These lecture notes cover all the basic concepts assumed in our lectures. 

In order to develop an hand-on experience on QCD calculation, we propose the students to calculate the %$pp \to H+X$%  cross section at NLO in the HEFT. The full computation is described [here Higgs.pdf]. Mathematica Notebooks are provided below which contain all the details of the calculation and the implementation in a simple Notebook which can calculate cross section production at NLO at the LHC.
