ATLAS Physics Objects: Status and Performance at 13 TeV

The ATLAS experiment is designed to study the proton-proton collisions produced at the Large Hadron Collider at CERN. During the early Run 2 data-taking period, the ATLAS trigger and data acquisition system has been used to collect a data sample useful to study the initial performance of the detector and physics objects at the new center-of-mass-energy of 13 TeV. This note describes in general the identification and reconstruction efficiencies, resolution and performance of the ATLAS physics objects by using proton-proton collisions collected since the spring until the summer of 2015.
