Large-$R$ $\gamma+$Jet $\textit{In Situ}$ Calibration

Jets are produced at immense rates in high energy hadron colliders, such as the LHC, and are invaluable tools for preforming particle physics research. Before jets can be used in analyses their interaction with the detector must be well understood and properly calibrated. This poster will describe the calibration of the $\textit{in situ}$ jet energy scale (JES) for large-$R$ jets (anti-$k_{t}$ $R = 1.0$) in the ATLAS experiment, as measured via the $\gamma+$jet direct $p_{\mathrm{T}}$ balance method from 35.7 fb$^{-1}$ of 2015-2016 data. In combination with other $\textit{in situ}$ measurements, these results improve the constraint on the large-$R$ JES to 1-2%. Reducing the JES systematic uncertainty is an important boost for many searches for new physics and hadronic standard model measurements.
