How to and FAQ's
General
- Structure flowchart
- How to install the whole Madgraph/MadEvent package on your machine and generate a new process
- Syntax and process input examples
- How to generate events on your machine
- Submission scripts and running on your cluster
- Testing the complex mass scheme implementation
FAQ's
- How do I implement my own cuts in MadEvent ?
- How do I implement my own renormalization/factorization scales in MadEvent ?
- How do I change the mass of a particle that is assumed massless in MadGraph/MadEvent ?
- Can I just calculate the amplitudes for a (sub)process and check them point-by-point in phase space points using MadGraph ?
- Is there a limit to the maximum allowed number of diagrams? How can I change it?
- How do I generate only a subset of diagrams? What are the decay chains?
- Can I use MadGraph (or any other external matrix element generator) with Pythia for DIS?
- How many events can I generate in one run with MadEvent?
- Can I use the LHE file from Pythia as input to detector simulation?
- I generated an s-channel process p p > W+ > e+ ve, and in some events the W doesn't show up in the event record. Why is this?
- How do I read the .hep file from Pythia?
- Why don't I get the number of events I asked for from MadEvent?
- What are the default dynamic factorization and renormalization scales in MadEvent?
- I have zero result Why?
Input Cards
FAQ's
- Should I use different ids (@1,@2,...) in multiprocess proc_card or could I use the same ?
- What is bwcutoff, and why is it important for decay chains?
Interfaces and Tools
FAQ's
- How I decay heavy particles in the final state?
- What is REPLACE?
- Pythia and HERWIG require a mass for all particles, while in MadGraph several are set to zero. How do I fix it?
- How to read the LHCO event files
- How do I get nice plots automatically when running generate_events, like I get on the web?
Matching/Merging with the Shower
FAQ's
Gridpacks
- Introduction to Grid running option in MG/ME
- Technical details for setting up and running the Grid Package
FAQ's
- Can I analyse only a part of the produced sample?
- Is there a minimal statistics suggested?
- The gridpack seems sometimes very large in size? Can I improve on this?
- I have downloaded a madevent.tar.gz package. Can I create the gridpack locally?
