Serialization record for one generated particle in event output. More...

#include <gEventDataCollection.h>

Data Fields
std::string	name
	Particle name when known, otherwise a source-format identifier.

int	pid = 0
	PDG id or source particle id.

int	type = 1
	Generator source type. For Lund input, `type` == 1 means Geant4-propagated.

int	multiplicity = 1
	Number of copies represented by this row.

double	p = 0
	Momentum magnitude in GEMC internal units.

double	theta = 0
	Polar angle in GEMC internal angular units.

double	phi = 0
	Azimuthal angle in GEMC internal angular units.

double	vx = 0
	Vertex x coordinate in GEMC internal length units.

double	vy = 0
	Vertex y coordinate in GEMC internal length units.

double	vz = 0
	Vertex z coordinate in GEMC internal length units.

Detailed Description

This lightweight structure mirrors GParticleRecord without depending on the gparticle module from gdata. It is used by event streamers to publish generated-particle metadata alongside detector hit banks.

The generated bank contains inline -gparticle definitions and every parsed -gparticlefile row. The generated_tracked bank contains inline -gparticle definitions and only the file rows propagated in Geant4, normally rows with type == 1.
