CEDAR: HepData, JetWeb and Rivet
A. G. Buckley · 2009
I describe the work of the CEDAR collaboration in developing tools for tuning and validating Monte Carlo event generator programs.The core CEDAR task is to interface the Durham Hep-Data database of experimental measurements to event generator validation tools such as the UCL JetWeb system -this has necessitated the migration of HepData to a new relational database system and a Java-based interaction model.The "number crunching" part of JetWeb is also being upgraded, from the FORTRAN HZTool library to the new C ++ Rivet system and a generator interfacing layer named RivetGun.Finally, I describe how Rivet is already being used as a central part of a new generator tuning system, and summarise two other CEDAR activities, HepML and HepForge.
