Detailed Description

DDG4 physics constructor that installs the G4HepEm vectorised EM tracking manager.

Replaces the Geant4 stepping loop for e-, e+ and gamma with G4HepEmTrackingManager, providing SIMD-vectorised EM physics.

A single G4HepEmTrackingManager instance is created per call to constructProcesses() and registered with all three particle types (e-, e+, gamma). This is the canonical G4HepEm usage pattern: G4HepEmTrackingManager::HandOverOneTrack() dispatches internally on particle type, so one shared instance handles all three species.

Geant4 owns and deletes the tracking manager.

Member Function Documentation

◆ constructProcesses()

virtual void dd4hep::sim::Geant4HepEmTrackingPhysics::constructProcesses ( G4VUserPhysicsList * )

inlineoverridevirtual

Callback to install the G4HepEmTrackingManager on e-, e+ and gamma.

Called from within G4VPhysicsConstructor::ConstructProcess() by the DDG4 action sequence, after ConstructParticle() has been executed.

Creates one G4HepEmTrackingManager and registers it with all three EM particle types. Ownership is transferred to Geant4: the pointer is stored (non-owning) inside each particle's TLS data slot, and G4VUserPhysicsList::RemoveTrackingManager() will delete it at thread / run teardown.

Reimplemented from dd4hep::sim::Geant4PhysicsList.
