Detailed Description

Formal class representing the milli-charged particle in Geant4.

This class follows the standard prototype for all G4ParticleDefinitions where a static private member holds onto the single instance of this particle definition to be shared by everyone. In this case, G4FractionallyCharged::Initialize needs to be called before any calls to G4FractionallyCharged::G4FractionallyCharged so that the simulation has a defined FCM mass.

The G4FractionallyCharged::Initialize call should be done in the ConstructParticle function of a physics constructor.

Constructor.

Passes all parameters to the base class constructor to register this particle definition with Geant4.

Member Function Documentation

◆ FractionallyCharged()

G4FractionallyCharged * G4FractionallyCharged::FractionallyCharged ( )

static

Accessor for FractionallyCharged definition.

Exceptions

std::runtime_error if the FractionallyCharged is not initialized yet.

See also: Initialize for configuring and constructing the FractionallyCharged at the start of a run.

◆ Initialize()

void G4FractionallyCharged::Initialize	(	double	mass,
		int	id = `17`,
		float	charge = `0.1`
	)

static

Initialize the FractionallyCharged particle with the passed configuration.

Exceptions

std::runtime_error if the FractionallyCharged has already been initialized

Parameters

[in]	mass	The mass of the FractionallyCharged in MeV
[in]	id	The PDG ID number to use for the FractionallyCharged particle The default value for the PDG ID is set to 17 as a 4th generation lepton whose charge is a free parameter which we can set to be a small fraction of e.

Here are the properties of the formal Geant4 fcp we define.
