 v1 ===== Exercise on recursive relations ===== Think about the computation of %$q \bar q + n \gamma$% in a recursive way, by Think about the computation of $q \bar q + n \gamma$ in a recursive way, by trying not calculate the same quantities twice. Show that the complexity of the calculation goes from %$n \cdot n!$% (factorial) to %$n \cdot 2^{n-1}$%  (exponential) . from $n \cdot n!$ (factorial) to $n \cdot 2^{n-1}$  (exponential) . === Going NLO  === === Selected exercises on QCD that can be solved with a Matrix Element generator. === * [: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 in pp collisions. * [:tt:top production] : %$t \bar t$% production, Tevatron vs LHC. * [: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]. * [wiki:DeadCone Radiation from heavy quarks]:  the dead cone in $e^+e^- \to Q \bar Q g$. * [wiki:GluonSpin Spin of the gluon]:  Vector vs scalar in the  angular correlations of $e^+ e^- \to$ 4 jets. * [wiki:2Jets Jets] : Di-jet kinematics and rates in pp collisions. * [wiki:3Jets 3 Jets] : Energy distributions in 3-jet events in pp collisions. * [wiki:tt top production] : $t \bar t$ production, Tevatron vs LHC. * [wiki:WAsymm Drell-Yan]: rapidity asymmetry at the Tevatron and LHC. * [wiki:TopDecaySpinCorrelations Spin correlations in top decay], by [http://www.hep.phy.cam.ac.uk/theory/webber/ Bryan Webber]. === Monte Carlo integration === === LHC Phenomenology === * [:DiscoverTheHiggs:SM Higgs discovery at the LHC]: Three important channels * [:WarmingUpChallenge:Simple Black Boxes]: New gauge bosons * [wiki:DiscoverTheHiggs SM Higgs discovery at the LHC]: Three important channels * [wiki:WarmingUpChallenge Simple Black Boxes]: New gauge bosons === How to familiarize with Software.MadGraph === * 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.
