This PR introduces several updates to the taskDeuteronFromLb analysis task:

  • Antihypertriton has been added as an additional mother particle of antideuterons.
  • Efficiency calculations have been implemented, including event-loss efficiency, signal-loss efficiency, and reconstruction efficiency.
  • 2D DCA histograms have been added. For each antideuteron production source, the task now provides DCA distributions, the mother-particle (c\tau) distribution, and the corresponding efficiencies.
  • Consistency between data and MC: The same track-quality cuts and PID selections applied to data are now also applied to reconstructed MC particles ("MCReco"), ensuring consistency between the two process functions.
  • TPC electron veto: An electron rejection veto based on the TPC PID response has been added.
  • TOF PID vetoes: Electron, pion, kaon, and proton rejection vetoes have also been added using the TOF PID response.
