| 英文摘要 | The wz production cross section is measured by the cms experiment at the cern lhc in proton proton collision data samples corresponding to integrated luminosities of 4.9 fb(-1) collected at root s = 7 tev, and 19.6fb(-1) at root s = 8 tev. the measurements are performed using the fully-leptonic wz decay modes with electrons and muons in the final state. the measured cross sections for 71 < m(z) < 111 gev are sigma (pp -> wz; root s = 7 tev) = 20.14 +/- 1.32 (stat)+/- 0.38 (theo)+/- 1.06 (exp)+/- 0.44 (lumi) pb and sigma (pp -> wz; root s = 8 tev) = 24.09 +/- 0.87 (stat) 0.80 (theo) +/- 1.40 (exp) +/- 0.63 (lumi) pb. differential cross sections with respect to the z boson p(t), the leading jet p(t), and the number of jets are obtained using the root s = 8 tev data. the results are consistent with standard model predictions and constraints on anomalous triple gauge couplings are obtained. |
