Detailed Description

A simple class to carry informations about hadronic interactions.

Since the primary is destroyed at each hadronic interaction point, in case of quasi-elastic interaction we will have a new "primary" with a different track ID. At each interaction point, the new primary will be recorded in primary, while the ID of the original primary will be stored in originalTrackID.

Member Function Documentation

Float_t* GGSTHadrIntInfo::GetInteractionPoint ( )

inline

The interaction point.

Simple getter that returns primary.pos.

Returns

Pointer to a Float_t[3] containing the (x,y,z) coordinates of the interaction point.

Definition at line 61 of file GGSTHadrIntInfo.h.

{ return primary.pos; }

int GGSTHadrIntInfo::GetNProducts

(

)

Returns the number of particles produced in the interaction.

Returns

The number of particles produced in the interaction (-1 if no information about products is available)

Definition at line 31 of file GGSTHadrIntInfo.cpp.

                                  {
  if (products) {
    return products->GetEntries();
  } else {
    return -1;
  }
}

GGSTParticle * GGSTHadrIntInfo::GetProduct

(

int

iProduct

)

Retrieves the particles produced in the interaction.

Parameters

iProduct

The desired produced particle.

Returns

Pointer to the produced particle (NULL if nProduct is out of range or if no info about products is available).

Definition at line 41 of file GGSTHadrIntInfo.cpp.

                                                      {
  int nProducts = GetNProducts();
  if (iProduct < nProducts && iProduct > -1) {
    return (GGSTParticle *)(products->At(iProduct));
  } else {
    return NULL;
  }
}

Field Documentation

GGSTParticle GGSTHadrIntInfo::primary

The particle originating the interaction.

The kinematic properties of the particle (position, momentum, time) are relative to the interaction point.

Definition at line 37 of file GGSTHadrIntInfo.h.

Int_t GGSTHadrIntInfo::targetPDGCode

PDG code of target nucleus.

A 10 digit number; the encoding is: +-100ZZZAAAI

I is always 0. See the documentation of GetNucleusEncoding on the page: http://geant4.cern.ch/bin/SRM/G4GenDoc.exe.pl?flag=2&FileName=G4IonTable.hh&FileDir=source/particles/management/include
