The main activity of this Task Force consists to monitor periodically - during the development of Geant4 - all the results of the physics validation effort of the Collaboration, and report to the Steering Board any inconsistency, degradation, or unexpected behaviour.
This Task Force relies heavily on the validation repository geant-val.
When an “anomalous” physics result is detected, in collaboration with the Electromagnetic and Hadronic Physics Groups, detail, dedicated investigations are carried out, first to understand the source of the problem, and then, possibly, to find a solution or at least a way to overcome the problem.
More extensive physics validation campains are undertaken for public releases and their patches, whereas for monthly, development snapshots, restricted sets of validation and regression tests, with reduced statistics, are executed.
