Detailed Description

The C++ interface class to Pythia6

According to TPythia6 class from Root: (The TPythia6 class is an interface class to F77 routines in Pythia6 // CERNLIB event generators, written by T.Sjostrand.) http://root.cern.ch/ see http://root.cern.ch/root/License.html

Constructor & Destructor Documentation

Pythia6::Pythia6 ( )

Pythia6 constructor: creates a vector of Pythia6Particle in which it will store all particles. Note that there may be only one functional Pythia6 object at a time, so it's not use to create more than one instance of it.

Referenced by G4Pythia6Decayer::ImportParticles().

Here is the caller graph for this function:

int Pythia6::ImportParticles	(	ParticleVector *	particles,
		const char *	option = `""`
	)

Default primary creation method. It reads the /HEPEVT/ common block which has been filled by the GenerateEvent method. If the event generator does not use the HEPEVT common block, This routine has to be overloaded by the subclasses. The function loops on the generated particles and store them in the TClonesArray pointed by the argument particles. The default action is to store only the stable particles (ISTHEP = 1) This can be demanded explicitly by setting the option = "Final" If the option = "All", all the particles are stored.

void Pythia6::Py1ent	(	int	line,
		int	kf,
		double	pe,
		double	theta,
		double	phi
	)

Add one entry to the event record, i.e. either a parton or a particle.

IP: normally line number for the parton/particle. There are two exceptions:

If IP = 0: line number 1 is used and PYEXEC is called. If IP < 0: line -IP is used, with status code K(-IP,2)=2 rather than 1; thus a parton system may be built up by filling all but the last parton of the system with IP < 0. KF: parton/particle flavour code (PDG code) PE: parton/particle energy. If PE is smaller than the mass, the parton/particle is taken to be at rest. THETA: PHI: polar and azimuthal angle for the momentum vector of the parton/particle.
