Pich, [http://arxiv.org/pdf/hep-ph/0502010 [hep-ph/0502010]]. * Lecture 3 : [:FurtherReading:Perspectives on LHC physics, Ed. by G. Kane and A. Pierce]. Answers to some of the questions asked during lecture can be found [:QandA:here]. === Tests and Exercises === The following tests help to understand the lectures better, and to prepare for the exercises related to the different lectures: * [:TestLecture1:Test for lecture 1]. * [:TestLecture2:Test for lecture 2]. A pdf with the exercises related to the lectures can be found [attachment:Exercises.pdf here].

Some of the exercises proposed can be "solved" or checked with Software.MadGraph / Software.MadEvent.

====== Introduction to hadron collisions ====== * [:SimpleKinematics:Kinematics at the LHC]: single particle quantities. * [:2Jets:Jets] : Di-jet kinematics and rates in pp collisions. * [:3Jets:3 Jets] : Energy distributions in 3-jet events. * [http://cp3wks05.fynu.ucl.ac.be/twiki/bin/view/Physics/WAsymm Drell-Yan] : Study the rapidity asymmetry at the Tevatron. ====== Higgs and top ====== * [:HiggsPheno:Higgs] : Higgs phenomenology at hadron colliders. * [:tt:top production] : %$t \bar t$% production, Tevatron vs LHC. ====== New Physics ====== * [:tprime:t' production] : %$t'$% production at the LHC. * [:X:New resonances]: Discover new resonances at the LHC. === Animations === * [http://madgraph.hep.uiuc.edu/Event/ Interactive Flash version] Note you may want to zoom in! * [http://madgraph.hep.uiuc.edu/Event/fast_collisionx6.avi Fast movie (.avi) of collision] * [http://madgraph.hep.uiuc.edu/Event/collision.mov Guided movie (.mov) of collision] === Familiarize with Software.MadGraph === * 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>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: 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 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].
