INTRODUCTION The succeurul operation of the CERN pp Collider [1] has given the opportunity to obtenrt experimeaully the eriitmcr of the IVB predicted by the by the unified electioweak theory [2]. This paps describe* some propertiei of the IVB decayi into both leptorue md hadronic rhiTTP^* as ineuurtd by the UAi lod UA2 ^^TTimniiti The iArr\iifirMirm of leptons is the UA1 and UA2 detecton u diy^^d The FVB masses ud the production crou lections (times branching ratioi) are measured for the different leptonic decayi These data provide the first teit of the univerulity of the weak couptiap between IVB ud leptoas it Q* « <&w'- A itudy of the oumber of light neutrino specie* at a function of the top mass is performed from the measured values of the W* and Z* decay widths.
