Here is how to familiarize with the code. 54 55 * Logon to the MadGraph web site and register. 56 57 * Familiarize with the code by generating a few processes in QED and QCD trying to guess which diagrams appear. What is the minimum number of jets have to be asked for in $e^+e^$ collisions so that the triple gauge vertex appear? 58 59 * Look at the new physics models and check the particle and interactions content. 60 61 * Generate events for a few selected processes and look at the plots: 62 * ttbar production with decays: pp>tt~>bb~mu+eve~vm 63 * VV production: pp>VV> leptons, with V=Z,W. 64 * Single top + Higgs: pp>tHj (QCD=0, QED=3, j=gudsc,p=gudscb). Show that there is a large negative interference between the diagrams 65 66  Main.FabioMaltoni  20130303 43  Main.FabioMaltoni  20130606 67 44 68 45
