Detailed Description

This service provides access to particle properties.

The settable property of this service is the ParticlePropertiesFile, an ASCII file containing the list of properties for the particles. The default file is: "$PARAMFILESROOT/data/ParticleTable.txt" or if $PARAMFILESROOT is not defined "ParticleTable.txt"

Author

Iain Last

Gloria Corti 8/11/1999 change default file from $CDF/particle.cdf to $LHCBDBASE/cdf/particle.cdf on Unix and use environment variable also on WinNT Also introduce finding of particle by StdHepID

Vanya BELYAEV

Date

2006-09-22 1) Modified to add possibility to redefine properties of existing particles and to read additional files. New property "OtherFiles" (default is empty vector) is introduces. Service parsed additional files after the main one.

// read additional properties
ParticlePropertySvc.OtherFiles = {
   "$SOMELOCATION1/file1.txt" ,
   "$SOMELOCATION2/file2.txt"
} ;

2) Add possibility to modify only certain particles through the new property "Particles" (default is empty list), Each line is interpreted as a line in particle data table, e.g.

// redefine the properties of H_20 and H_30 particles:
ParticlePropertySvc.Particles = {
    "H_20 88 35 0.0 120.0 9.4e-26 Higgs'0 35 0.0e+00" ,
    "H_30 89 36 0.0  40.0 1.0e-12      A0 36 0.0e+00"
  } ;

The replaces/modified particles are reported.

override

Create a new particle property.

Create a particle property and insert it in the maps.

Attention

ParticlePropertySvc IS the owner if this property! String name of the particle.

Parameters

geantId	Geant3 ID of the particle.
jetsetId	Jetset ID of the particle.
charge	Particle charge (/e).
mass	Particle mass (GeV).
tlife	Particle lifetime (s).
evtName	String name of the particle in EvtGen.
pythiaId	Pythia ID of the particle.
