Detailed Description

GPhysics is a thin integration layer between GEMC options and the Geant4 extensible physics list factory. It is not derived from G4VModularPhysicsList; instead, it creates a physics list instance and returns a pointer to it via getPhysList().

The physics list selection is driven by options defined in gphysics::defineOptions(), most notably:

• phys_list : the reference physics list string (with optional extensions).
• showPhysics : a switch that prints the available physics lists and constructors and exits early.

Ownership note: The returned G4VModularPhysicsList pointer is expected to be managed by the Geant4 application lifecycle (typically by the run manager). This class does not delete the physics list.

Constructor & Destructor Documentation

GPhysics()

GPhysics::GPhysics

(

const std::shared_ptr< GOptions > &

gopts

)

The constructor reads the relevant options from the provided GOptions instance:

• If the showPhysics switch is enabled, the constructor prints the available Geant4 lists/constructors and returns without creating a physics list.
• Otherwise, it requests the reference physics list specified by the phys_list option and registers additional constructors required by the module defaults.

Parameters

gopts

Shared options container used to retrieve phys_list and showPhysics.

Returns

Pointer to the G4VModularPhysicsList created by this module, or nullptr if the list could not be created or if showPhysics was requested.
