CMS : Jet and missing $E_{T}$ reconstruction

The performance of jet and missing transverse energy (MET) reconstruction at the CMS experiment in LHC Run 2 data will be shown. The efficiencies of the reconstruction at the High Level Trigger will be discussed first, followed by the performance of the pileup mitigation techniques used in the jet and MET selection. The jet energy scale corrections used at the CMS experiment will be described, as well as the MET cleaning and reconstruction performance. The conclusions will be outlined with respect to the performance of jet and MET objects, with prospects for future studies.
