Measurement of the ratio of the 3-jet to 2-jet cross sections in pp collisions at s=7 TeV

Abstract: A measurement of the ratio of the inclusive 3-jet to 2-jet cross sections as a function of the total jet transverse momentum, , in the range is presented. The data have been collected at a proton?proton centre-of-mass energy of 7 TeV with the CMS detector at the LHC, and correspond to an integrated luminosity of 36 pb?1. Comparisons are made between the data and the predictions of different QCD-based Monte Carlo models for multijet production. All models considered in this study are consistent with the data for . This measurement extends to an range that has not been explored before.
