| 6 | |
| 7 | A short introduction to the techniques of Monte Carlo integration. Exercises proposed during lecture |
| 8 | are collected in this Mathematica Notebook: [attachment:mc101.nb mc101.nb]. |

| 10 | === Exercises === |
| 11 | |
| 12 | All exercises proposed here can be "solved" or checked with Software.MadGraph / Software.MadEvent. |
| 13 | |
| 14 | ==== Software.MadGraph prolegomena ==== |
| 15 | |
| 16 | * Logon to the Software.MadGraph web site and register. |
| 17 | |
| 18 | * 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? |
| 19 | |
| 20 | * Look at the new physics models and check the particle and interactions content. |
| 21 | |
| 22 | * Generate events for a few selected processes and look at the plots: |
| 23 | * ttbar production with decays: pp>tt~>bb~mu+e-ve~vm |
| 24 | * VV production: pp>VV> leptons, with V=Z,W. |
| 25 | * Single top + Higgs: pp>tHj (QCD=0, QED=3, j=gudsc,p=gudscb). Show that there is a large negative interference between the diagrams |
| 26 | |
| 27 | |
| 28 | ==== QCD ==== |
| 29 | |
| 30 | * Reference: [http://www.hep.phy.cam.ac.uk/theory/webber/QCDbook.html QCD and Collider Physics] |
| 31 | by Keith Ellis, James Stirling, Bryan Webber (Cambridge Monographs, 1996). |
| 32 | |
| 33 | * [:DeadCone:Radiation from heavy quarks]: the dead cone in %$e^+e^- \to Q \bar Q g$%. |
| 34 | * [:GluonSpin:Spin of the gluon]: Vector vs scalar in the angular correlations of %$ e^+ e^- \to$% 4 jets. |

| 41 | * Reference: Lecture notes on the Standard Model and Book, by [http://www.ge.infn.it/~ridolfi/ Giovanni Ridolfi]. |
| 42 | |
| 43 | * [:GammaZ:%$\gamma Z$% interference] in %$e^+e^- \to \mu^+ \mu^-$%. |
| 44 | * [:HiggsLep:Higgs at LEP] : the cross section for %$e^+e^- \to ZH$% at LEP2. |

| 51 | |
| 52 | === LHC Phenomenology === |
| 53 | |
| 54 | * Analysis routines for LHE and LHCO events: |
| 55 | * a Fortran-based package: Software.MadAnalysis ([http://madgraph.phys.ucl.ac.be/cgi-bin/NewProcess/download.cgi Download it here]) |
| 56 | * a Mathematica-based package: [http://www.jthaler.net/olympics/software.html Chameleon]. |
| 57 | * [:SimpleKinematics:Kinematics at the LHC]: single particle quantities. |
