Abstract

Results on the production cross sections of W and Z bosons detected in the UA2 experiment are given based on a large sample of W→eν and Z→e+e- decays. The measured cross sections are σW e = 660±15(stat)±37(syst)pb, σZ e = 70.4±5.5(stat)±4.0(syst)pb and their ratio R=9.38-0.72 +0.82(stat)±0.25(syst). In the framework of the Standard Model, the measured value of R is used to determine the total width of the W, Γ(W)=2.30±0.19(stat)±0.06(syst) GeV.
