| 62 | === Familiarize with Software.MadGraph === |
| 63 | |
| 64 | * Logon to the Software.MadGraph web site and register: http://madgraph.hep.uiuc.edu. |
| 65 | |
| 66 | * Familiarize with the code by generating a few processes in QED + QCD trying to guess which diagrams appear. |
| 67 | |
| 68 | * Look at the new physics models and check the particle and interactions content. |
| 69 | |
| 70 | * Generate events for a few selected processes and look at the plots: |
| 71 | * ttbar production with decays: pp>tt~>bb~mu+e-ve~vm |
| 72 | * VV production: pp>VV> leptons, with V=Z,W. |
| 73 | * Single top + Higgs: pp>tHj (QCD=0, QED=3, j=gudsc,p=gudscb). Show that there is a large negative interference between the diagrams. |
| 74 | |
| 75 | === Analysis Tools === |
| 76 | |
| 77 | * a Fortran-based package: Software.MadAnalysis ([http://madgraph.phys.ucl.ac.be/cgi-bin/NewProcess/download.cgi Download it here]) |
| 78 | * a Mathematica-based package: [http://www.jthaler.net/olympics/software.html Chameleon]. |
