Reconstruction of jets and missing transverse momentum at the CMS experiment: Run 2 and perspective for Run 3

TL;DR

This paper discusses the performance and calibration of jets and missing transverse momentum in CMS during Run 2, and explores new techniques planned for Run 3 to improve reconstruction accuracy in proton-proton collisions at 13 TeV.

Contribution

It presents the latest tools for jet and missing transverse momentum reconstruction, calibration, and pileup mitigation, with an outlook on future techniques for Run 3.

Findings

Improved jet and missing transverse momentum reconstruction in Run 2 data

Effective pileup mitigation techniques implemented

Future techniques for Run 3 outlined

Abstract

The performance of reconstruction and calibration of jets and missing transverse momentum in the CMS Collaboration, together with the latest tools for pileup mitigation, is presented. The results shown are relative to the data collected from 2016 to 2018 (Run 2) in proton-proton collisions at a centre-of-mass energy of 13 TeV. An outlook to the new techniques foreseen for Run 3 is discussed.
