Rates of Jets Produced in Association with W and Z Bosons
arXiv:1110.0213
Abstract
Presented here is a study of jets produced in association with vector bosons production in pp collisions at \surds = 7 TeV using the full CMS 2010 data set, corresponding to an integrated luminosity of 36 \pm 1.4 pb-1. The transverse energy distribution of the reconstructed leading jets is measured and compared to theoretical expectations. The jet multiplicity distributions are corrected for efficiency and unfolded. The ratios of multiplicities, σ(V+ \geq n jets)/σ(V+ \geq (n - 1) jets) and σ(V+ \geq n jets)/σ(V) where n stands for number of jets, are also presented along with the first test of the Berends-Giele scaling at \surds = 7 TeV.
