Are all the HLT triggers listed under the dataset in the CMS Open Data portal applied to the dataset? Or is it just a suggestion of the HLT triggers we can apply to the dataset during our analysis?
It’s a list of the triggers that have been applied to record the data set, but with a logical OR. For your analysis, you should generally apply at least one.
So how to know which among them was used at the time of the recording
Hi, we have a trigger tutorial available in Introduction to the CMS Trigger It was a part of the CMS open data workshop in July: CERN (Virtual): Jul 19-22, 2021)
Let us know if that helps!
Best, Kati
