Simulation in LHCb

This page is intended to hold fast evolving information on the simulation and to allow contributions by all. More information is available from the Gauss official web site that is cross referenced to this site.

Some topics in these pages may be not up to date, in which case they are indicated with Warning, important (May-Be-)Not-Up-To-Date. If you find something is no longer up to date, please tag it as such.

Topic being worked on are indicated with Work in progress, under construction In-Work.


Gauss is the LHCb Simulation software, built on the Gaudi Framework.
It consist of a first phase where the events are generated (e.g. pp collisions at 14 TeV) and a second phase where the particles are propagated trough the LHCb detectors.


The Gauss integration and release manager is Gloria Corti. The list of topics and coordinators/contacts is here.
