[Charm] Tune hadronic doubly charmed baryon lines for Run 2025
Tune hadronic doubly charmed baryon lines based on 2024 data blocks 7-8 and simulation W40.42.
Major changes are:
- Fix too tight MAXDOCA cut for multi-body Hc and Hcc decay
- Remove HTL1 filtering, which was used as a fast solution last year and but shown not optimal by MC
- Apply PROBNN cuts for final-state tracks
- Tune cuts on final-state tracks considering Q-value and lifetime of mother particles
- Tune cuts on Hc and Hcc considering lifetime and n-body decays
- Remove DIRA cut and persist
pv_tracksfor golden channels for lifetime measurement - Simplify code structure for easier configuration
These changes lead to:
- Increase of efficiency by around 10% - 30% depending on modes
- Decrease of BW for
ccbaryon_hadronicmodule from 19.4 MB/s to 10.8 MB/s by running 1M events atroot://eoslhcb.cern.ch//eos/lhcb/wg/rta/WP3/mdfs_hlt1filtered_307586
