NAME

module AnaEventDefinition

PURPOSE

Here type(tAnaEvent) is defined. Routines to work with this type are defined elsewhere, as e.g. in module AnaEvent

AnaEvent/particleIDs [ Global module-variables ]

[ Top ] [ AnaEvent ] [ Global module-variables ]

PURPOSE

The ID's of the particles we consider "stable". For these detailed analyses can be performed as determined by namelist &detailed_diff public is necessary because it is used in LArAnalysis

numStableParts = dimension of array particleIDs = number of stable particles for which final state analyses will be done. numStableMesons is number of long-lived mesons (width < 1E-4 GeV)

NOTE: all the stable particles also have to be listed in subroutine event_add which is contained in module AnaEvent

For higher energies more, heavier hadrons may appear. For these the array has to be extended together with numStableParts and numStableMesons

AnaEventDefinition/tAnaEvent [ Types ]

[ Top ] [ AnaEventDefinition ] [ Types ]

NAME

Type tAnaEvent

PURPOSE

Type definition for events. The first index in numberParticles runs over all stable hadrons used in the analysis + 1, (numStableParts + 1), the second one over the possible charge states (-2 -> +2)

SOURCE

  Type tAnaEvent
     sequence
     type(tParticleList) :: particleList                 ! particles in the event
     integer,dimension(1:14,-2:2) :: numberParticles =0  ! Counters for stable particles
                                                         ! (under strong decays)
  End Type tAnaEvent

NOTES

The field numberParticles includes the multiplicities of particles. Antiparticles are not counted!
