=== MC101 ===

A short introduction to the techniques of Monte Carlo integration. Exercises proposed during lecture
are collected in this Mathematica Notebook:  [attachment:mc101.nb mc101.nb].

=== Exercises ===

    All exercises proposed here can be "solved" or checked with Software.MadGraph / Software.MadEvent.

==== Software.MadGraph prolegomena ====

   * Logon to the Software.MadGraph web site and register. 

   * 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? 

   * Look at the new physics models and check the particle and interactions content.

   * Generate events for a few selected processes and look at the plots:
      * ttbar production with decays: pp>tt~>bb~mu+e-ve~vm
      * VV production: pp>VV> leptons, with V=Z,W.  
      * Single top + Higgs: pp>tHj  (QCD=0, QED=3, j=gudsc,p=gudscb). Show that there is a large negative interference between the diagrams
      
   
==== QCD ====

   * Reference: [http://www.hep.phy.cam.ac.uk/theory/webber/QCDbook.html QCD and Collider Physics] 
      by Keith Ellis, James Stirling, Bryan Webber (Cambridge Monographs, 1996).

   * [:DeadCone:Radiation from heavy quarks]:  the dead cone in %$e^+e^- \to Q \bar Q g$%.
   * [:GluonSpin:Spin of the gluon]:  Vector vs scalar in the  angular correlations of %$ e^+ e^- \to$% 4 jets.
   * [:2Jets:Jets] : Di-jet kinematics and rates in pp collisions. 
   * [:3Jets:3 Jets] : Energy distributions in 3-jet events.
   * [:tt:top production] : %$t \bar t$% production, Tevatron vs LHC. 

==== EW ====

   * Reference: Lecture notes on the Standard Model and Book, by [http://www.ge.infn.it/~ridolfi/ Giovanni Ridolfi].

   * [:GammaZ:%$\gamma Z$% interference] in %$e^+e^- \to \mu^+ \mu^-$%.
   * [:HiggsLep:Higgs at LEP] : the cross section for %$e^+e^- \to ZH$% at LEP2.
   * [:WAsymm:Drell-Yan]: rapidity asymmetry at the Tevatron and LHC.
   * [:TopDecaySpinCorrelations: Spin correlations in top decay], by [http://www.hep.phy.cam.ac.uk/theory/webber/ Bryan Webber].

==== BSM ====
   * On-line [http://kraml.web.cern.ch/kraml/comparison SUSY LHA file generator]  by Sabine Kraml.
   * Lorenzo Basso's model Software.MadGraph implementation: [attachment:basso.tar.gz basso.tar.gz]

=== LHC Phenomenology ===

   * Analysis routines for LHE and LHCO events: 
      * a Fortran-based package: Software.MadAnalysis ([http://madgraph.phys.ucl.ac.be/cgi-bin/NewProcess/download.cgi Download it here])
      * a Mathematica-based package: [http://www.jthaler.net/olympics/software.html Chameleon].
   * [:SimpleKinematics:Kinematics at the LHC]: single particle quantities.
   * [:DiscoverTheHiggs:SM Higgs discovery at the LHC]: Three important channels
   * [:WarmingUpChallenge:Simple Black Boxes]: New gauge bosons
 
=== Challenges ===
