Description

The measurement of the jet energy scale using data from sqrt(s) = 13 TeV collisions is presented. A sequence of Monte­Carlo based calibrations restore jets to the particle scale and use jet properties to significantly improve the jet resolution. A combination of measurements using Z+jet, gamma+jet, and multi­jet events is used to calibrate jets in data and to measure systematic uncertainties. A 5% data/MC difference is observed, and corrected for, at low pT. Uncertainties are as low as 1% at p_T^{jet} of 200 GeV, and for the first time in­situ measurements are extended to 2 TeV. More data from the 2016 run is expected to further reduce uncertainties and improve the results.
