### MC101

A short introduction to the techniques of Monte Carlo integration. Exercises proposed during lecture are collected in this Mathematica Notebook: mc101.nb.

### Exercises

All exercises proposed here can be "solved" or checked with Software.MadGraph / Software.MadEvent.

• 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. What is the minimum number of jets have to be asked for in %% collisions so that the triple gauge vertex appear?
• Look at the new physics models and check the particle and interactions content.
• Generate events for a few selected processes and look at the plots:
• ttbar production with decays: pp>tt~>bb~mu+e-ve~vm
• VV production: pp>VV> leptons, with V=Z,W.
• Single top + Higgs: pp>tHj (QCD=0, QED=3, j=gudsc,p=gudscb). Show that there is a large negative interference between the diagrams

#### QCD

by Keith Ellis, James Stirling, Bryan Webber (Cambridge Monographs, 1996).

• [:GluonSpin:Spin of the gluon]: Vector vs scalar in the angular correlations of %% 4 jets.
• [:2Jets:Jets] : Di-jet kinematics and rates in pp collisions.
• [:3Jets:3 Jets] : Energy distributions in 3-jet events.
• [:tt:top production] : %% production, Tevatron vs LHC.

#### EW

• [:GammaZ:%% interference] in %%.
• [:HiggsLep:Higgs at LEP] : the cross section for %% at LEP2.
• [:WAsymm:Drell-Yan]: rapidity asymmetry at the Tevatron and LHC.
• [:TopDecaySpinCorrelations: Spin correlations in top decay], by Bryan Webber.

### LHC Phenomenology

• Analysis routines for LHE and LHCO events:
• [:SimpleKinematics:Kinematics at the LHC]: single particle quantities.
• [:DiscoverTheHiggs:SM Higgs discovery at the LHC]: Three important channels
• [:WarmingUpChallenge:Simple Black Boxes]: New gauge bosons
