TPythia is an interface class to F77 version of Pythia 6.2.

To use this class you must install a version of pythia6. See the installation instructions at http://root.cern.ch/root/Install.html

CERNLIB event generators, written by T.Sjostrand. For the details about these generators look at Pythia/Jetset manual:

Int_t TPythia6::ImportParticles	(	TClonesArray *	particles,
		Option_t *	option = `""`
	)

virtual

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.

TObjArray * TPythia6::ImportParticles ( Option_t * option = "" )

virtual

Fills TObjArray fParticles list with particles from common LUJETS Old contents of a list are cleared.

This function should be called after any change in common LUJETS, however GetParticles() method calls it automatically - user don't need to care about it. In case you make a call to LuExec() you must call this method yourself to transfer new data from common LUJETS to the fParticles list.

Calls PyInit with the same parameters after performing some checking, sets correct title.

This method should preferably be called instead of PyInit. PURPOSE: to initialize the generation procedure. ARGUMENTS: See documentation for details.

frame: - specifies the frame of the experiment: "CMS","FIXT","USER","FOUR","FIVE","NONE"
beam,
target: - beam and target particles (with additionaly charges, tildes or "bar": e,nu_e,mu,nu_mu,tau,nu_tau,gamma,pi,n,p,Lambda,Sigma,Xi,Omega, pomeron,reggeon
win: - related to energy system:
- for frame=="CMS" - total energy of system
- for frame=="FIXT" - momentum of beam particle
- for frame=="USER" - dummy - see documentation.

void TPythia6::Py1ent	(	Int_t	ip,
		Int_t	kf,
		Double_t	pe,
		Double_t	theta,
		Double_t	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.
