Ultra-Fast Simulation of LHCb

Review of the beta version

The aim of the review is to evaluate the status of the software in view of a beta release of Delphes in Gauss.

The beta release should have the following functionality:

  • Code for the propagation of charged particles and parameterised efficiency and resolution
  • Code for the propagation of neutral particles (gamma and pi0)
  • Code for the simulation of the Rich and Muon detectors
  • Code for the parametrization of primary vertices
  • Parametrization for at least one data taking conditions and a mechanisms to select/load other conditions
  • Transparent steering of Delphes via the Gauss() configurable

Their status and technical implementation as well as the implication of the choices made will be presented.

The review will also cover

  • Timing measurements, disk space, i.e. computing requirements
  • Plans and methods for testing and validation
  • Options for production and user tests
  • Identification of the remaining features to make Delphes-in-Gauss a fully functional Monte Carlo option for physics analysis and planning for their implementation
  • Strategy for the migration to the future Gauss-on-Gaussino simulation framework. In particular the mitigation of design changes for Multi-threading and migration to HepMC 3 should be presented
  • Method to obtain parameterization from data and expected studies to establish the granularity needed for data taking conditions
