Doubt regarding list of HLT Triggers in CMS Open data portal

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
