Modify the selection for the derivation HDBS5
Hello,
We hope to change the selection for the derivation HDBS5 to get a higher signal efficiency. This is the previous merge request for this derivation: !56685 (merged)
And the jira ticket for this new derivation: https://its.cern.ch/jira/browse/ATLHDBSDPD-129
With this update, the data efficiency changes from 1.6% to 1.8%, and the MC dominant background efficiency increases from 10% to 11.5%. The size of each event is similar to before. Thanks!
