     15   * [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). General introduction QCD. The section on top is an easy and efficient reading to learn the basics.

     17   * [http://arxiv.org/abs/hep-ph/0003033 Top physics at the LHC], by Beneke et al. : A complete document, though a bit outdated, that covers many of the interestings studies that will be performed at the LHC. A very useful reference.
     18
     19   * [http://arxiv.org/abs/0805.1333 Top Physics at the LHC], by Werner Bernreuther : A nice and up-to-date overview on top physics at the LHC. It has also a complete reference list that can be used for further studies.

     21   * [http://arxiv.org/abs/hep-ph/9612329 Top mass definition], by M. Smith and S.Willenbrock. This is an easy and very clear discussion that it will make you appreciate the subtleties associated to a meaningful definition of a mass of a quark.

     46=== Familiarize with Software.MadGraph ===
     47
     48A brief tutorial on Software.MadGraph / Software.MadEvent can be found [attachment:mad-tutorial.pdf here].
     49
     50   * Logon to the Software.MadGraph web site and register: http://madgraph.hep.uiuc.edu.
     51   * Familiarize with the code by generating a few processes in QED + QCD trying to guess which diagrams appear.
     52   * Look at the new physics models and check the particle and interactions content.
     53   * Generate events for a few selected processes and look at the plots:
     54      * ttbar production with decays: pp&gt;tt~&gt;bb~mu+e-ve~vm
     55      * Single top + Higgs: pp&gt;tHj (QCD=0, QED=3, j=gudsc,p=gudscb). Show that there is a large negative interference between the diagrams.
     56
     57Analysis Tools
     58
     59   * a Fortran-based package: Software.MadAnalysis ([http://madgraph.phys.ucl.ac.be/cgi-bin/NewProcess/download.cgi Download it here])
     60   * a Mathematica-based package: [http://www.jthaler.net/olympics/software.html Chameleon].

     64For those interested in Monte Carlo techniques, here is a short Mathematica course with applications to top physics:
     65
     66   * Write the simplest integration function based on the definition of average and error
     67   * Importance sampling via an analytic transformation
     68   * Von Neumann's rejection method : plain and improved
     69   * Phase space for 1 -&gt; n particles
     70   * Vegas
     71   * Top decay : comparison among the various methods
     72   * qq -&gt; tt production
     73
