Split B2ppbarhh into four different channels
patch generated by https://gitlab.cern.ch/lhcb/Moore/-/jobs/37133956
Using a bandwith snippet: https://gitlab.cern.ch/-/snippets/2694 the size of obtained data sample for all three lines is 2.0MB, while 28 events are triggered based on 50K events. The test sample is "expected_2024_min_bias_hlt1_filtered" ** Calculated bandwidth of all three divided lines 0.0478 GB/s **
Consider the large rate caused by noPID lines, #717 (comment 7667283)
then try with split them and perform PID for h
. Some data following. The rate at least decrease to one third while the effect on efficiency is acceptable.
Rate with PID
B→pppipi: (0.023000000 +- 0.000999995)%
B→ppKpi: (0.02100000 +- 0.00458209)%
B→ppKK:(0.007000000 +- 0.00264566)%
noPID:
(0.1800000 +- 0.0423882)%
Efficiency with PID
B→ppkpi: (0.6471260 +- 0.110622)%, B→pppiK: (0.6471260 +- 0.110622)%
(B→ppKpi+pppiK: ( 1.199086 +- 0.150162)%)
B→pppipi: (0.9229349 +- 0.145254)% (0.7152746 +- 0.128007))%
B→ppKK: (0.9505703 +- 0.149582)%
···
without PID
B→pppipi:( 1.338256 +- 0.174542)% B→ppKK: ( 1.259506 +- 0.171913)% B→ppKpi:( 1.332318 +- 0.158178)%
