 v1 == (Accurate simulation) tools for collider physics TASI 2013 == 3 Lectures MC's developments for the LHC. 3 lectures MC's developments for the LHC by Fabio Maltoni and 3 tutorials on FeynRules/MadGraph by Celine Degrande and Olivier Mattelaer. === Lectures === The PDF of the lectures  be found here: [attachment:TASI3.pdf MC3: Merging and matching] The examples and exercises are related to physics at the LHC. ==== Tests and exercises ==== === Basic aspects of QCD === We provide here complimentary material to the lectures that can used by students to verify their understanding of the basic concepts. ===== Monte Carlo integration ===== ===== Various Tests and exercises ===== 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 ===== * [wiki:DiscoverTheHiggs SM Higgs discovery at the LHC]: Three important channels * [wiki:WarmingUpChallenge Simple Black Boxes]: New gauge bosons A collection of test, exercises, and web applications on pQCD can be found in [https://cp3.irmp.ucl.ac.be/projects/madgraph/attachment/wiki/CernSchool2011/QCD-exercises.pdf QCD-exercises.pdf]. === Going NLO === ==== Going NLO ==== 1. pp>H at LO (1-loop): details of the calculation (Mathematica Notebook) [https://cp3.irmp.ucl.ac.be/projects/madgraph/attachment/wiki/CernSchool2011/HiggsGG-LO-mtfinite.nb HiggsGG-LO-mtfinite.nb] A summary of the results can be found in [attachment:QCDHiggs.pdf QCDHiggs.pdf]. === Selected exercises on QCD that can be solved with a Matrix Element generator. === * [wiki:DeadCone Radiation from heavy quarks]: the dead cone in $e^+e^- \to Q \bar Q g$. * [wiki:GluonSpin Spin of the gluon]: Vector vs scalar in the angular correlations of $e^+ e^- \to$ 4 jets. * [wiki:2Jets Jets] : Di-jet kinematics and rates in pp collisions. * [wiki:3Jets 3 Jets] : Energy distributions in 3-jet events in pp collisions. * [wiki:Tt top production] : $t \bar t$ production, Tevatron vs LHC. * [wiki:WAsymm Drell-Yan]: rapidity asymmetry at the Tevatron and LHC. * [wiki: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 === * [wiki:DiscoverTheHiggs SM Higgs discovery at the LHC]: Three important channels * [wiki:WarmingUpChallenge Simple Black Boxes]: New gauge bosons === How to familiarize with MadGraph === All exercises proposed can be "solved" or checked with MadGraph / MadEvent. Here is how to familiarize with the code. * Logon to the 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 - 2013-03-03 -- Main.FabioMaltoni - 2013-06-06
