Start from #305 (closed), implementing the comment #305 (comment 5363235).
This MR will add a new PID substitution Tool and a new DTF Tool for DaVinci, which has integrated the PID substitution. A minimal example of the usage could be:
DTF_KstG = DecayTreeFitter(
Name = 'DTF_KstG',
Input = B_Data,
Substitutions = [
' B0 -> ( K*(892)0 -> K+ K-{{pi-}} ) gamma',
]
)
variables_all = FC({
# Original particle
'ORIGINAL_ID' : F.PARTICLE_ID,
'ORIGINAL_ENERGY' : F.ENERGY,
'ORIGINAL_CHI2DOF' : F.CHI2DOF,
# DTF Bd2KstGamma
'DTF_KSTG_ID' : F.VALUE_OR(-1) @ DTF_KstG.get_info( F.PARTICLE_ID ),
'DTF_KSTG_ENERGY' : DTF_KstG.get_info( F.ENERGY ),
'DTF_KSTG_CHI2DOF' : DTF_KstG.get_info( F.CHI2DOF ),
})A real example could be found in https://gitlab.cern.ch/lhcb/DaVinci/-/blob/jzhuo_SubsPID/DaVinciExamples/python/DaVinciExamples/tupling/option_davinci_tupling_DTF_substitutePID.py
Other example for SubstitutePID without DTF could be found in https://gitlab.cern.ch/lhcb/DaVinci/-/blob/jzhuo_SubsPID/DaVinciExamples/python/DaVinciExamples/tupling/option_davinci_tupling_substitutePID.py
This MR should be test with DaVinci!756 (merged)
