A novel method to measure the jet energy resolution from dijet events at CMS — •Yannick Fischer1, Johannes Haller1, Andrea Malara2, Alexander Paasch1, and Matthias Schröder1 — 1Universität Hamburg — 2Université Libre de Bruxelles
The jet energy is a key observable for almost all analyses at the CMS experiment at the CERN LHC. A precise knowledge of the jet energy resolution (JER) is crucial for both measurements and searches. This talk will give a brief overview over JER measurements at CMS. A novel method based on the missing transverse momentum fraction (MPF) technique is introduced. The new approach provides a JER measurement complementary to existing methods and aims at avoiding several of their dominant uncertainties. In this talk, we will introduce the new method and show first results with the recent CMS data.
