d02kshh analysis production for Run3 data

Maurizio Martinelli requested to merge d02kshh_run3 into master

Analysis production of Run3 data for D02Kshh decays. Tuples are made out of the following HLT2 Turbo lines (from Hlt2Charm):

D⁰→K⁰ₛπ⁺π⁻ D⁰→K⁰ₛK⁺π⁻ D⁰→K⁰ₛK⁻π⁺ D⁰→K⁰ₛK⁺K⁻
D0ToKsPimPip_LL D0ToKsKpPim_LL D0ToKsKmPip_LL D0ToKsKmKp_LL

The first commit is a copy-paste from Charm/2024-validation. A significant reduction of the size of the tuples is expected by the application of the following selection cuts:

  • z(K^0_S) - z(D^0) > 10 (220) mm for LL (DD)
  • PIDe(π_s) < 0

Other selection cuts are applied on t/\tau(D^0) and p_T(D^0) depending on the trigger condition and the sample

p_T(D^0) > x MeV/c LL LL (LowBias) LL (NoBias) DD DD (LowBias)
D^* TIS 3500 5000 3500 4000 5000
D^0 OTMVA - 4000 4000 - -
D^0 TTMVA - - 4000 - -
D^0 D2Kshh - 3000 3000 - -
K^0_S TTKs 4000 5000 4000 - -
t/\tau(D^0) > x LL LL (LowBias) LL (NoBias) DD DD (LowBias)
D^* TIS 0.5 0.5 0.5 0.5 0.5
D^0 OTMVA 0.2 0.5 0.5 0.2 0.2
D^0 TTMVA 0.2 0.2 0.2 0.2 0.2
D^0 D2Kshh 0.5 0.5 0.5 - -
K^0_S TTKs 0.2 0.4 0.5 - -

By applying the above cuts, the retention rate dropped as shown in the table:

Job name Original (GB) With Cuts (GB) Retention (%)
d0_to_kshh_27165903_2024_MagUp_Nu7p6_HLT1,2,MC_ 7.0 4.8 68
d0_to_kshh_27165903_2024_MagDown_Nu7p6_HLT1,2,MC_ 8.6 5.8 67
d0_to_kshh_27165903_2024_MagUp_Nu5p7_HLT1,2,MC_ 3.7 2.5 68
d0_to_kshh_27165903_2024_MagDown_Nu5p7_HLT1,2,MC_ 3.9 2.5 64
d0_to_kshh_2024_MagUp 50900 2600 5
d0_to_kshh_2024_MagDown 16580 806 5

To Do

  • Implement selection cuts
  • Add monitoring histogram with D^0, K^0_S, and ∆m mass before and after the selection
  • Add monitoring histogram on D^0 lifetime

n.b. histograms are not persisted at the moment.
