Jet energy scale and resolution measurement with Run 2 Legacy Data Collected by CMS at 13 TeV (CMS DP-2021/033)

Link to DPS note on CDS

Main Results

Jet energy correction (JEC) and resolution (JER) measurement is presented here are based on data collected in 2016-2018 with legacy reconstruction.

Previous results for end of year (EOY) reconstruction are shown here. The main detector changes are related to the phase-1 upgrade of the Pixel tracker, which took place between the 2016 and 2017 data taking periods, and to the calorimeter thresholds that have been modified for each year.
