This section of the tutorial goes through the process of adding and analyzing various objects that we detect with ATLAS. We will go through three of the big ones: electrons, muons, and jets (+ discussions on missing transverse energy).
A required step when we analyze our objects is to perform calibration and selections. Each CP group defines their own tools and functions to assist us with this process. We are going to take a look at some typical ways we apply the hard work of the CP groups to our analysis.
The general formula for adding object information to our ntuples is similar to what we did for the events:
