 v1 == !MonteCarlo and Event generators for the LHC, == == Zuoz July 2010. == 2 Lectures are given on MC's developments for the LHC. The PDF of the lectures can be found [attachment:maltoni-zuoz-2010.pdf here]. The examples and exercises are related to physics at the LHC. === Basic aspects of QCD === Here I collect some material for exercises that is actually mostly covered by Frank's [http://ltpth.web.psi.ch/zuoz2010/lectures/petriello/petriello_PSI10.pdf lectures]. ===== Various Tests and exercises ===== A collection of test, exercises, and web applications on the basics of pQCD can be found in [attachment:QCD-exercises.pdf QCD-exercises.pdf]. ===== Going NLO ===== 1. pp>H at LO (1-loop): details of the calculation (Mathematica Notebook) [attachment:HiggsGG-LO-mtfinite.nb HiggsGG-LO-mtfinite.nb] 1. pp>H at NLO: details of the calculation (Mathematica Notebook) [attachment:HiggsGG-NLO.nb higgsGG-NLO.nb] 1. pp>H at NLO: cross section evaluation for the LHC (Mathematica Notebook+PDF libraries to be compiled) [attachment:phenHiggs.tar.gz phenHiggs.tar.gz]. A summary of the results can be found in [attachment:Higgs.pdf Higgs.pdf]. === Selected exercises on QCD that can be solved with a Matrix Element generator. === * [: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 in pp collisions. * [:tt:top production] : %$t \bar t$% production, Tevatron vs LHC. * [:WAsymm:Drell-Yan]: rapidity asymmetry at the Tevatron and LHC. * [:TopDecaySpinCorrelations: Spin correlations in top decay], by [http://www.hep.phy.cam.ac.uk/theory/webber/ Bryan Webber]. === Monte Carlo integration === A short introduction to the techniques of Monte Carlo integration. Exercises proposed during lecture are collected in this Mathematica Notebook: [attachment:mc101.nb mc101.nb]. === LHC Phenomenology === * [:DiscoverTheHiggs:SM Higgs discovery at the LHC]: Three important channels * [:WarmingUpChallenge:Simple Black Boxes]: New gauge bosons === How to familiarize with Software.MadGraph === All exercises proposed can be "solved" or checked with Software.MadGraph / Software.MadEvent. Here is how to familiarize with the code. * 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 -- Main.FabioMaltoni - 2010-07-28
