d_to_hhh lines optimization 2025

Gustavo Alejandro Loachamin Ordonezrequested to merge
d_to_hhh_update into charm_2025_reopt

Changes applied to d_to_hhh lines to reduce the rate:

  • DIRA > (cos(14.1)->cos(10)).

  • (Hlt1TrackMVA_TOS||Hlt1TwoTrackMVA_TOS)|| (Hlt1TrackMVA_TIS||Hlt1TwoTrackMVA_TIS) filter applied.

  • The lines Hlt2Charm_DpDspToKmKpPip_NoCuts and Hlt2Charm_DpDspToKmPipPip_NoCuts are commented out since the IPChi2<20 cut was disabled for the main lines

  • A summary of the studies performed on these lines is shown in the attached file.d_to_hhh_optimization.pdf
