CMS Analysis Information

In CMS the relevant information about how to handle physics objects in your analysis which includes recommendations for triggers, object identification, calibration, correction etc. is provided by the Physics Object Groups (POGs).

The information is collected in either a CERN Twiki page or wiki docs:

There is also additional information specifically for the scale factors and how to evaluate them using correctionlib. This tool is used in CROWN.

Further, common analysis recommendations, which are not specifically relevant for CROWN but for the subsequent analysis steps like CMS plotting style, naming of systematic uncertainties or statistical tools, can be found here: https://cms-analysis.docs.cern.ch/
