Jet energy resolution measurement at CMS — Roman Kogler, •Marek Niedziela, Christian Sander, and Hartmut Stadie — Institute of Experimental Physics, Luruper Chaussee 149, D-22761 Hamburg, Germany

At the LHC, the collision of coloured particles are often producing many jets in the final state. Precise measurements and searches for deviations from predictions of the Standard Model require a precise understanding of these objects. In particular, the jet energy resolution is of great importance. It has to be measured for jets as a function of their kinematic properties, such as the transverse momentum p_T and the pseudorapidity η. At 7 and 8 TeV, measurements of jet resolutions have been carried out using the transverse momentum balance of γ+jets or di-jet events. In this presentation, the first jet energy resolution measurements from CMS at 13 TeV, applying the same technique, will be presented.
