+
+=== References ===
+
+   * [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.
+
+   * [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 : A complete document, though a bit outdated, that covers many of the interestings studies that will be performed at the LHC.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.
+
+   * [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.
+
+   * [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.
+
+=== Exercises ===
+
+Decay
+
+   * [:TopWidth:Top width]: Calculate the width of the top quark.
+   * [:DeadCone:Radiation from heavy quarks]: the dead cone in %$e^+e^- \to Q \bar Q g$%.
+   * [:TopDecaySpinCorrelations: W+ polarization in top decays].
+
+Production
+
+   * [:tt:top production] : %$t \bar t$% production and single top at Tevatron vs LHC.
+   * [:scalar:scalar vs fermion top cross sections at hadron colliders] : Compare the production of scalar and fermion heavy color triplets in hadron collisions.
+   * [:SpinCorr:Spin Correlations in top production]
+
+=== Light material on the heaviest quark ===

+
+=== Familiarize with Software.MadGraph ===
+
+A brief tutorial on Software.MadGraph / Software.MadEvent can be found [attachment:mad-tutorial.pdf here].
+
+   * Logon to the Software.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&gt;tt~&gt;bb~mu+e-ve~vm
+      * 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.
+
+Analysis Tools
+
+   * 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].
+
+=== MC101 ===
+
+For those interested in Monte Carlo techniques, here is a short Mathematica course with applications to top physics:
+
+   * 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 -&gt; n particles
+   * Vegas
+   * Top decay : comparison among the various methods
+   * qq -&gt; tt production
+
+All exercises are presented and solved this Mathematica Notebook: [attachment:mc101.http://cp3wks05.fynu.ucl.ac.be/twiki/pub/Physics/TAE2008/mc101.nb mc101.nb].
