Fix for bug in one of the PIDe lines and added extra cuts
One of the PIDe lines, Hlt2PID_BToJpsiK_JpsiToEmbremEpbremTagged, used a wrong function and that was producing fewer events from it. With this bug resolved, now works as expected.
Additionally, we added two extra cuts (B_BPVIPCHI2<30 and B_BPVDIRA>0.8) to make the selection a bit better and be able to see a peak out of the box. This extra selection, tested using 2023 data and mc, has the following efficiency tested in the line without the bug, Hlt2PID_BToJpsiK_JpsiToEpbremEmbremTagged, and the equivalent one without PIDe cut on the tag:
- PIDe on tag:
- MC efficiency of 98.64%
- BKG rejection of 86.33%
- noPIDe on tag:
- MC efficiency of 99.46%
- BKG rejection of 34.56%
