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.

Introduction

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.

Coordinators

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

Gauss Web

The main Gauss web page containing release information and links to user guides and tutorials, is here.

Documentation

Current and future developments

Bugs and features

To report new bugs or unexpected feature use the "LHCb Physics software" savannah portal and select "Simulation" as category.

You can also check the list of already known bugs and their status.

MC Piquet

A report on the status of the MC Requestsis presented every two weeks at the PPTS meeting. Instructions for those preparing the report can be found here.

Future releases
