Draft: Algorithm to select persistable particles in charm HLT2 lines for baryon spectroscopy

Ryunosuke O'Neil requested to merge roneil-bach-sel into master

An algorithm designed to be used in Charm HLT2 selective persistence (SP) lines for baryon spectroscopy, to cut down on event size.

It is based on GetFlavourTaggingParticles by @cprouve with the following extensions

  • accepts v2 primary vertices
  • LoKi tools are not used to find BPVs and MIPCHI2
  • performs a vertex fit and check if the vertex is good between the baryon candidate and bachelor candidate
    • require the fit to succeed
    • require the fit chi2 per dof to be below a specified value
  • performs a deltaR calculation and rejects particles if they do not fall inside a specified deltaR region
