B&Q: Xibc/Tbc -> J/psi + hadrons

Ivan Polyakov requested to merge ipolyako_onia_Hbc into master

adding several more lines for Xibc & Tbc -> Jpsi + hadron decays which have similar final states: tested on 100 events of Jpsi-preselected output of Hlt2 (from scripts by @mengzhen !1997 (merged)). Verified that script runs and corresponding lines do not prompt an error, but no estimation on efficiencies - log files accessible in /afs/cern.ch/work/i/ipolyako/public/Run3/stack/Moore/Hlt/Hlt2Conf/options/bandq/spruce_opt_test.log

The line for Xibc+->Jpsi D0 p K- pi+ is commented out in sprucing due to unavailability of 5-body particle combinations. Changes in Rec & Moore suggested (Rec!3721 (merged) and !2000 (merged))

Also small changes in

  • longlived_hadrons: added merged Ks0
  • c_hadrons / c_to_hadrons: added a D0->K3pi decay mode and merged D0 "aimed for spectroscopy" ( D0->K-pi+, D0->K3pi). I do not include KK & pipi modes as they're x10 suppressed wrt Kpi and K3pi, therefore give no gain in statistics for spectroscopy studies.
