[QEE] Use the optimised PIDmu value for the EW quarkonia caliibration samples

Luke Grazette requested to merge lugrazet-qee-qonia-pidmu into qee_upgrade

As was discussed !3418 (comment 7952644), We find an optimum of PIDmu > -10, keeping 99% of the signal, and removing ~63% of the bkg. Intended to be added in !3418 (merged) but a mistake in git (on my part 🤦) caused this to be overriden to > 0 in the final state of the MR.

Now fixed and thus much improving our signal efficiecny, expected very small increase in BW, negligible in the testing.

BW Evaluation

10k via https://gitlab.cern.ch/-/snippets/3187, evaluated on this MR and on qee_upgrade (9fabc422)

We see a small increase in Rate for the QEE turbo stream, O(100 Hz), and no difference in BW.

ToDo:

  • local BW tests. Expected no change in the precision of the test.
