1. M.G. Pia on behalf of the Physics Book Team
Geant4 Workshop
Bordeaux, 7-10 November 2005

2. Previous agreements Focus on validation of basics Geant4 physics
Validation in a set of typical use cases
Electromagnetic + Hadronic volume
…but nature does not distinguish physics into volumes
Address electromagnetic volume first, hadronic volume at a later stage (after 2007)
to be revised?
“Chapters” of the Book are published as topical papers in refereed journals

3. Current status Electromagnetic 1st paper published (NIST validation)
Bremsstrahlung in progress
atomic relaxation
Electromagnetic + hadronic
Bragg peak
Small team actively involved in the project
very few young collaborators + few senior experts

4. Outlook
It would be desirable to invest a wider collaboration effort into the Physics Book
hadronic physics validation in parallel with electromagnetic one
larger team involved in the validation activities
cover more domains (scintillation, Cherenkov, optical, muon processes etc.)
Identify relevant data sources
Investigate publication strategy
