◆ ImportParticles() [1/2]

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

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.

Reimplemented from TGenerator.

Definition at line 326 of file TPythia6.cxx.

◆ ImportParticles() [2/2]

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.

Reimplemented from TGenerator.

Definition at line 363 of file TPythia6.cxx.

◆ Initialize()

void TPythia6::Initialize ( const char *  frame,
const char *  beam,
const char *  target,
float  win 
)

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.

◆ Instance()

◆ Py1ent()

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.
