MCatNLO howto

Running MCatNLO

This page describes how to generate $t{\bar {t}}$events in using the MCatNLO generator. The description describes what we did for the Rome production and is set up so that you can start from scratch. Since most people will produce various sets of events, some python scripts have been included. They are certainly not brilliant, but provide you with a working starting point.

The three steps to success when using MCatNLO

Producing events in ATLAS using MCatNLO can be split up in three separate steps:

1. MCatNLO Integration step and producing the executable
2. Generating events
3. Top decay and producing an ntuple using Atlfast (athena)
