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 TeV.Comment: 8 pages, 10 figures, Meeting of the Division of Particles and Fields
