Abstract
This thesis describes an experiment performed with the UA1 detector at the Spp-barS at CERN on the production and decay of W{sup {+-}} bosons in proton-antiproton collisions. In particular the total width of the W{sup {+-}} resonance has been determined. A direct measurement of this quantity already exists, but with an uncertainty of 70%. Here an indirect method is presented in which this quantity is inferred from the ratio of the W {yields}lv and Z {yields} ll-bar partial cross sections measured at pp-bar colliders and the total width of the Z boson, accurately measured at LEP. It exploits the complementary results of pp-bar and e{sup +}e{sup -} machines and allows to bring down the uncertainty on the total width to about 8%. The results is compared with the Standard Model prediction and its implication for the mass of the top quark is investigated. Also the possibility to put a constraint on the masses of the new elementary particles predicted by the Super Symmetry model is considered. (author). 126 refs.; 67 figs.; 23 tabs.
