Tests and Exercises
The following tests help to understand the lectures better, and to prepare for the exercises related to the different lectures:
A pdf with the exercises related to the lectures can be found here.
Some of the exercises proposed can be "solved" or checked with MadGraph / MadEvent.
Introduction to hadron collisions
- Kinematics at the LHC: single particle quantities.
- Jets : Di-jet kinematics and rates in pp collisions.
- 3 Jets : Energy distributions in 3-jet events.
- Drell-Yan : Study the rapidity asymmetry at the Tevatron.
Higgs and top
- Higgs : Higgs phenomenology at hadron colliders.
- top production : $t \bar t$ production, Tevatron vs LHC.
New Physics
- t' production : $t'$ production at the LHC.
- New resonances: Discover new resonances at the LHC.
Animations
- Interactive Flash version Note you may want to zoom in!
- Fast movie (.avi) of collision
- Guided movie (.mov) of collision
Familiarize with MadGraph
- Logon to the MadGraph web site and register: http://madgraph.hep.uiuc.edu.
- Familiarize with the code by generating a few processes in QED + QCD trying to guess which diagrams 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.
Analysis Tools
- a Fortran-based package: MadAnalysis (Download it here)
- a Mathematica-based package: Chameleon.
MC101
For those interested in Monte Carlo techniques, here are some exercises:
- Write the simplest integration function based on the definition of average and error
- Importance sampling via an analytic transformation
- Von Neumann's rejection method : plain and improved
- Phase space for 1 -> n particles
- Vegas
- Top decay : comparison among the various methods
- qq -> tt production
All exercises are presented and solved this Mathematica Notebook: mc101.nb. Reference: Introduction to MC methods, by Stefan Weinzierl
