B2OC: Improvements to dstar_to_dzeropi builder and adjustments to certain b builder thresholds (shifters PLEASE ignore)

Fionn Caitlin Ros Bishop requested to merge b2oc-fibishop-dstar-and-b2dd into b2oc_upgrade

In dstar_to_dzeropi and dstar_to_dzeropi_cf:

  • Remove 600MeV mass window
  • Redefine deltaM cut to use F.MASS - F.CHILD(1, F.MASS) instead of F.MASS-_DST2010_M
  • Reduce deltamass_max from 200 to 180MeV
  • Set default bpvvdchi2_min to None
  • Set default bpvdira_min to None
  • Set default soft_pi_pidk_max to None
  • Set default soft_pi_p_min to 0GeV
  • Set default soft_pi_pt_min to 0MeV
  • Set default soft_pi_mipchi2_min to 0
  • Supersedes !1437 (closed)

In _make_b2dd and _make_b2dstd:

  • Make vtx_chi2pdof_max and bpvipchi2_max values the same as those used in equivalent bc builders

Temporary fixes for certain lines involving a D*+ to keep retentions below 55/100K:

  • MVAcut=0.35 for BuToDstmhh_DstmToD0Pi_D0ToHH, XibToDstmph_DstmToD0Pi_D0ToHH lines
  • make_b2cstarhh uses make_b2chh defaults for bcvtx_sep_min and sum_pt_min
