            |   | 53 | All exercises proposed can be "solved" or checked with MadGraph / MadEvent. Here is how to familiarize with the code. | 
          
          
            |   | 54 |  |

            |   | 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+e-ve~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 |
