15:30 → 16:00 Break

16:00 → 18:00 Parallel session 8A : Hadronic Discussion

• Muon stopping
• How to treat consistently "hybrid processes", like electro-nuclear; the problem of hadronic dependencies
• Better modularization of the hadronic physics library, e.g. compiling G4 without CHIPS
• Trends in G4PhysicsConstructor and complete physics lists
• How to make hadronics workable for nuclear physics
• Any topic that has not been properly covered during the previous four hadronic sessions, or that needs
  further discussion.

- formalism, design
- final state biasing
