WP S - Detailed and Fast Simulation¶
The simulation of the event of interest through the experimental setup is the necessary step to follow their generation. It can be performed with either a detailed modelling of the geometry and physical processes occurring or via faster counterparts.
Mandate¶
The mandate of the Detailed and Fast Simulations Work Package, WP S, is:
To ensure the maintenance and ongoing development of the simulation phase of gauss
To maintain the software interface to the Geant4 toolkit and keep up to date with Geant4 collaboration updates.
To explore new modelling in Geant4, improve the Geant4 cuts applied and choice of physics processes.
To maintain and develop dedicated validation tools as necessary.
To monitor physics and performance of fast and detailed simulation.
To manage LHCb-specific extensions to the simulation frameworks and Geant4.
To improve and ensure integration of current and future developed fast simulation techniques, and their evolution to new technologies.
To provide guidelines on the usability of each fast simulation technique.
To provide tools for evaluating systematic effects based on the choice of fast simulation technique when relevant.
The WP is responsible for the adoption of new versions of Geant4 and their release in the LHCb software stack. It also triggers the release of new fast simulations within Gauss.
For these reasons, close collaboration with WP F and WP D is essential.
