【 摘 要 】

The measurements of the cross-sections are presented for the production of jets in association with 𝑊 and 𝑍 bosons reconstructed in their decays to electrons and muons. The results are based on 36 pb-1 of 𝑝𝑝 collisions at $sqrt{s} = 7$ TeV collected by the CMS Collaboration. Jets are reconstructed with the CMS particle flow algorithm and must pass a transverse momentum threshold of 30 GeV. The study presents the ratios $𝜎 (V + ≥ n-{ext{jet}})/𝜎 (V)$ and $𝜎 (V + ≥ n-{ext{jet}})/𝜎(V + ≥ (n - 1)-{ext{jet}}).$ The comparison between the data and the Monte Carlo prediction is also showed.
