Vector Boson plus Jets background to the early MET plus Jets Search

A search in large missing transverse momentum (MET) plus jets final state topology has great potential for discovery of new physics involving dark matter candidates early in LHC running. Some Standard Model processes produce the same observable signature. One of the main background is expected to...

description A search in large missing transverse momentum (MET) plus jets final state topology has great potential for discovery of new physics involving dark matter candidates early in LHC running. Some Standard Model processes produce the same observable signature. One of the main background is expected to be from higher order QCD contributions to single vector boson, which is difficult to predict with Monte Carlo. A strategy to estimate this contribution from data for the early search with the CMS detector using different control samples is presented.
