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.

Software.MadGraph prolegomena

  • 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 %$e^+e^-$% 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).

  • [:DeadCone:Radiation from heavy quarks]: the dead cone in %$e^+e^- \to Q \bar Q g$%.
  • [:GluonSpin:Spin of the gluon]: Vector vs scalar in the angular correlations of %$ e^+ e^- \to$% 4 jets.
  • [:2Jets:Jets] : Di-jet kinematics and rates in pp collisions.
  • [:3Jets:3 Jets] : Energy distributions in 3-jet events.
  • [:tt:top production] : %$t \bar t$% production, Tevatron vs LHC.

EW

  • [:GammaZ:%$\gamma Z$% interference] in %$e^+e^- \to \mu^+ \mu^-$%.
  • [:HiggsLep:Higgs at LEP] : the cross section for %$e^+e^- \to ZH$% at LEP2.
  • [:WAsymm:Drell-Yan]: rapidity asymmetry at the Tevatron and LHC.
  • [:TopDecaySpinCorrelations: Spin correlations in top decay], by Bryan Webber.

BSM

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
