Quick fix of BW in RD sprucing lines

The BW of RD sprucing lines were higher than expected in !4352 (closed). The cause if likely because GEC was removed from the inclusive detached dilepton triggers, and this change was not included in the local tests performed in !4352 (closed). This MR aims to improve the BW on these lines.

Most of the BW comes from the lines SpruceRD_{BuToHp,B0ToHpHm}{EE,MuMu}{_SameSign}.

To reduce the rate, the following changes are implemented to FULL stream lines:

  • Tightened B vertex chi2 cut from 20 to 16 in all inclusive detached dilepton lines

These changes are done to sprucing lines:

  • Removed topo as input to all btoxll sprucing lines
  • Tightened B vertex chi2 from 20 to 16
  • Tightened all hadron IP chi2 cuts by 1 unit
  • Tightened PID_MU from -3 to -2.5
  • Tightened lower end of B mass window in dielectron lines from 4.2 GeV to 4.3 GeV
  • Tightened electron PT cuts from 100 MeV to 200 MeV in BuToHpLL and 250 MeV in B0ToHpHmLL
  • Tightened DOCA chi2 cut on Jpsi from 36 to 20 on muon lines (cut is already at 10 for electron lines)
  • Tightened Jpsi vertex chi2 cut from 30 to 20
  • Added a Kst IP chi2 cut of 6 (8) to B0ToHpHmMuMu (EE)
  • Tightened some existing prescales in btosmutau_exclusive_spruce.py
  • Fixed bug in standard_particles.py where momentum cut was not applied

These changes reduced the output file size from 26MB to 14MB, so a BW reduction of 86%. The rest was performed by first running HLT2 on 2024 data with mu = 5.3, using 500 000 events. Only the topo lines, inclusive detached dilepton lines and cut-based dilepton lines were run. Finally, all RD sprucing run lines were run.
