Update of RD baryonic lines for 2025 June TS

Miroslav Saurrequested to merge
msaur_rd_baryonic_2025summer into rd-devel-june25

Collection of updates for RD baryonic lines aiming to be deployed post June TS.

Various cuts and improvements based on studies of practically equivalent multibody BnoC lines.

Implemented:

  • removing lifetime cut from generic RD Lambda0 combiners
  • refactoring and adding dedicated filter for Lambda0
  • Fixing kaon cut in Hlt2RD_LbToPpKmPipPimEE
  • Update cuts for Xim/Omm
  • Updating F.CHI2 to F.CHI2DOF
  • Tighter dielectron cuts (based on b_to_v0ll module)

New lines:

  • XibmToL0KmMupMum LL/DD ; rate < 13 Hz
  • XibmToL0pimMupMum LL/DD ; rate < 13 Hz
  • XibmToL0KmMuE LL/DD ; rate of DD line ~ 13 Hz, LL < 13 Hz
  • XibmToL0PimMuE LL/DD ; rate of DD line ~ 13 Hz, LL < 13 Hz
  • Physics motivation: study of degenerated heavy neutrinos with and without LNV; 2503.16293

Bandwidth rate:

  • 2025-patches: ~ 6.1 MB/s
  • This MR: ~ 7.5 MB/s
  • Change: + ~ 1.4 MB/s - mainly due to dielecton lines
