UA2 collaboration; Ansari, R. et al.
Measurement of the Standard Model Parameters from a Study of W and Z Bosons
Phys. Lett. 186B (1987) 440;

Abstracts
A study has been made of the decays W e and Z e+e-, using the UA2 detector at the CERN p Collider. The data correspond to an integrated luminosity of 142 nb-1 at a centre-of-mass collision energy = 546 GeV, and 768 nb-1 at = 630 GeV. Measurements of the standard model parameters from samples of 251 W decay and 39 Z decay candidates are compared with expectations of the standard electroweak model.
