Final modifications of lines targeting strange decays for 2025 data-taking
Goals
Include additional modifications to lines selecting strange decays. No major refactoring of the builders or the line definition will be applied in this set of changes. Modifications include:
-
use more meaningful and robust names, especially for lines selecting downstream decays -
check requirements on downstream lines -
check requirements on electrons -
tune the prescales -
improve the line docstrings and update the CODEOWNERS -
Revisit \Sigma\to p\pi^0, with \pi^0 dalitz
Changes
- Added four new lines, targeting same-sign cases for K_S^0\to\pi^+\pi^- e^+ e^-
- Improved electron requirements to be more efficient at a similar rate
- Improved downstream line requirements to be more efficient at a similar rate
- Improved requirements on some of the K_S^0 detached lines to increase efficiency at a similar rate
- Tuned the prescales
- Tweaked line names
