class HParticleFiller: public HReconstructor

_HADES_CLASS_DESCRIPTION


  HParticleFiller - Identifies particles using HCut classes

  This task fills the HParticle container by iterating over HKickTrack
  and HRichHit and identifying leptons with an angular correlation.  This
  class is still evolving... further pid and matching tools (showers,
  p.c. analysis, etc.) are being added.

  An HParticle is assigned its four-momentum compoments and other
  characteristics from HKickTrack (and rotated into cave coordinate
  system).  If an HParticle has an angular correlation with an HRichHit,
  the particle is assigned to be an electron (positron) if the track's
  charge in HKickTrack was -1 (+1).  2-d cuts are then applied to assign
  pid to hadrons.

  By calling the task with skip='kTRUE', events without an HParticle
  are skipped.  Currently, tracks from HKickTrack which do not have a
  valid pid are kept and assigned pid=0 (as in HKickTrack).
For more information, see the PhyAna documentation.

Function documentation

HParticleFiller(void)
 Default constructor
HParticleFiller(const Text_t* name, const Text_t* title, Bool_t skip = kFALSE)
 Consructor: Name, title, Skip event
Bool_t init(void)
 Creates/gets the KickTrack, RichHit and Particle categories in
 the current event
Int_t execute(void)
 Fills the Particle container using input from HKickTrack and HRichHit.
void fillMomenta(HKickTrack* track, HParticle* part)
 Fill components of 4-vector by rotating track into cave and
 calculating the coordinates.  If the particle has a PID, mass is
 calculated using particle mass from look-up table.  Otherwise,
 mass from HKickTrack is used.
void fillVertex(HKickTrack* track, HParticle* part)
 For now, this function simply fills HParticle's r and z directly
 from HKickTrack.  Eventually a vertex class could be implemented.
void makeLepton(HRichHit* ring, HParticle* part)
 Make a lepton out of an HParticle by reassigning mass and
 recalculating energy
~HParticleFiller(void)
{;}
void setCutTrack(HCutTrack* cutTrack)
{ trackCuts = cutTrack; }
HCutTrack* getCutTrack()
{ return trackCuts; }
void setCutLeptonId(HCutLeptonId* cutLepton)
{ leptonCuts = cutLepton; }
HCutLeptonId* getCutLeptonPid()
{ return leptonCuts; }
void setCutHadronId(HCutHadronId* cutHadron)
{ hadronIdCuts = cutHadron; }
HCutHadronId* getCutHadronPid()
{ return hadronIdCuts; }
Bool_t finalize(void)
{return kTRUE;}
