Calibration of b-jet taggers at the ATLAS experiment — •Johannes Hessler, Daniel Britzger, and Stefan Kluth — Max-Planck-Institut für Physik

Flavor tagging describes the identification of jets originating from heavy quarks in high energy physics. It plays an important role in many analyses at the ATLAS experiment.

This talk will discuss the calibration of the most recent machine learning based ATLAS b-jet taggers. The focus will be on the c-jet mistag rate. It accounts for the misidentification of c-jets as b-jets.
