B2KShh' BF analysis/Eff determination
-
Previous presentation (18/04/2025)
- I presented the average efficiencies after the ProbNNp < 0.5 cut for KK
- Unexpected increase with respect to the current version of the ANAnote
- I presented the average efficiencies after the ProbNNp < 0.5 cut for KK
Why?
- After some checks (see back up), I noticed that the efficiencies in the ANAnote already take into account this cut
- Current ANanote efficiencies: Previous sWeights + ProbNNp<0.5 cut for KK
- Tristan added the current tables on 18/07/2024
- One should compare instead with this ANAnote version (v4 27/06/2024).
- Current ANanote efficiencies: Previous sWeights + ProbNNp<0.5 cut for KK

Summary

May 2025
B2KShh' BF analysis/Eff determination
- The issue reported in the last presentation was a matter of a comparison with the wrong version of the efficiency tables
- A comparison with the correct version aligns well with the expected results for the KK mode:
- An almost negligible change of O(~2%) for Run 1 datasets
- A significant impact of O(~30%) for Run 2 samples
Why?
- On the efficiency side, it is okay to go ahead with the final combination
