=== Tests and Exercises ===

The following tests help to understand the lectures better, and to prepare for the exercises related to the different lectures:
   * [wiki:TestLecture1 Test for lecture 1].
   * [wiki:TestLecture2 Test for lecture 2].

A pdf with the exercises related to the lectures can be found [attachment:Exercises.pdf here]. [[br]]
Some of the exercises proposed can be "solved" or checked with MadGraph / MadEvent. [[br]]

=== Familiarize with MadGraph  ===

   * Logon to the MadGraph web site and register: http://madgraph.hep.uiuc.edu. 

   * Familiarize with the code by generating a few processes in QED + QCD trying to guess which diagrams 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.

=== Analysis Tools ===

   * a Fortran-based package: MadAnalysis ([http://madgraph.phys.ucl.ac.be/cgi-bin/NewProcess/download.cgi Download it here])
   * a Mathematica-based package: [http://www.jthaler.net/olympics/html Chameleon].

=== MC101 ===

For those interested in Monte Carlo techniques, here are some exercises:

   * Write the simplest integration function based on the definition of average and error
   * Importance sampling via an analytic transformation
   * Von Neumann's rejection method : plain and improved
   * Phase space for 1 -> n particles
   * Vegas
   * Top decay : comparison among the various methods
   * qq -> tt production

All exercises are presented and solved this Mathematica Notebook:  [attachment:mc101.nb mc101.nb].
