MadEvent: Automatic event generation with MadGraph
Aug, 2002Citations per year
Abstract:
We present a new multi-channel integration method and its implementation in the multi-purpose event generator MadEvent, which is based on MadGraph. Given a process, MadGraph automatically identifies all the relevant subprocesses, generates both the amplitudes and the mappings needed for an efficient integration over the phase space, and passes them to MadEvent. As a result, a process-specific, stand-alone code is produced that allows the user to calculate cross sections and produce unweighted events in a standard output format. Several examples are given for processes that are relevant for physics studies at present and forthcoming colliders.- programming

- kinematics: phase space
- anti-p p: annihilation
- p p: interaction
- intermediate boson: hadroproduction
- intermediate boson: pair production
- jet: associated production
- quark: pair production
