     3== QCD and MC tools for the LHC, Martigano June 2010. ==
     55 Lectures are given on QCD and MC's developments for the LHC. at the LHC.
     7The PDF of the lectures can be found [attachment:maltoni-martignano-2010.pdf here].
     9The examples and exercises are related to physics at the LHC.
     10=== Basic aspects of QCD ===
     11===== Various Tests and exercises =====
     13A collection of test, exercises, and web applications on pQCD can be found in [attachment:QCD-exercises.pdf QCD-exercises.pdf].
     15===== Exercise on recursive relations =====
     17Think about the computation of q \bar q + n \gamma in a recursive way, by trying not calculate the same quantities twice. Show that the complexity of the calculation goes from n! (factorial) to 2^{n-1} (exponential) .
     18=== Going NLO ===
     20   1. pp>H at LO (1-loop): details of the calculation (Mathematica Notebook) [attachment:HiggsGG-LO-mtfinite.nb HiggsGG-LO-mtfinite.nb]
     21   1. pp>H at NLO: details of the calculation (Mathematica Notebook) [attachment:HiggsGG-NLO.nb higgsGG-NLO.nb]
     22   1. pp>H at NLO: cross section evaluation for the LHC (Mathematica Notebook+PDF libraries to be compiled) [attachment:phenHiggs.tar.gz phenHiggs.tar.gz].
     24A summary of the results can be found in [attachment:Higgs.pdf Higgs.pdf].
     26=== Selected exercises on QCD that can be solved with a Matrix Element generator. ===
     28   * [:DeadCone:Radiation from heavy quarks]: the dead cone in %$e^+e^- \to Q \bar Q g$%.
     29   * [:GluonSpin:Spin of the gluon]: Vector vs scalar in the angular correlations of %$ e^+ e^- \to$% 4 jets.
     30   * [:2Jets:Jets] : Di-jet kinematics and rates in pp collisions.
     31   * [:3Jets:3 Jets] : Energy distributions in 3-jet events in pp collisions.
     32   * [:tt:top production] : %$t \bar t$% production, Tevatron vs LHC.
     33   * [:WAsymm:Drell-Yan]: rapidity asymmetry at the Tevatron and LHC.
     34   * [:TopDecaySpinCorrelations: Spin correlations in top decay], by [ Bryan Webber].
     36=== Monte Carlo integration ===
     38A short introduction to the techniques of Monte Carlo integration. Exercises proposed during lecture are collected in this Mathematica Notebook: [attachment:mc101.nb mc101.nb].
     40=== LHC Phenomenology ===
     42   * [:DiscoverTheHiggs:SM Higgs discovery at the LHC]: Three important channels
     43   * [:WarmingUpChallenge:Simple Black Boxes]: New gauge bosons
     45=== How to familiarize with Software.MadGraph ===
     47All exercises proposed can be "solved" or checked with Software.MadGraph / Software.MadEvent. Here is how to familiarize with the code.
     49   * Logon to the Software.MadGraph web site and register.
     51   * Familiarize with the code by generating a few processes in QED and QCD trying to guess which diagrams appear. What is the minimum number of jets have to be asked for in %$e^+e^-$% collisions so that the triple gauge vertex appear?
     53   * Look at the new physics models and check the particle and interactions content.
     55   * Generate events for a few selected processes and look at the plots:
     56      * ttbar production with decays: pp>tt~>bb~mu+e-ve~vm
     57      * VV production: pp>VV> leptons, with V=Z,W.
     58      * Single top + Higgs: pp>tHj (QCD=0, QED=3, j=gudsc,p=gudscb). Show that there is a large negative interference between the diagrams
