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, {\sigma}(V+ \geq n jets)/{\sigma}(V+ \geq (n - 1) jets) and {\sigma}(V+ \geq n jets)/{\sigma}(V) where n stands for number of jets, are also presented along with the first test of the Berends-Giele scaling at \surds = 7 ...
