Estimating QCD backgrounds at CMS detector with Rebalance and Smear method — Sam Bein1, Simon Kurz1, •Marek Niedziela1, Christian Sander2, Peter Schleper1, and Jory Sonneveld1 — 1Institut für Experimentalphysik Universität Hamburg — 2DESY
Searches for new physics in the CMS and ATLAS experiments at the LHC rely on accurate predictions of backgrounds, especially from QCD processes.
A method for predicting this QCD background called "rebalance and smear" has been developed for a search of new physics in the CMS collaboration that is based on multijet events with large missing transverse momentum produced in 13 TeV proton-proton collisions. The performance of rebalance and smear technique is compared with an alternative QCD background estimation method.
