Abstract
QCD one-loop corrections to the full gauge invariant set of electrowea k diagrams describing the hadronic process e(+)e(-) --> u (d) over bar s (c) over bar are computed. Four-jet shape variables for WW events a re studied at next-to-leading order and the effects of QCD corrections on the determination of the W-mass in the hadronic channel at Lep 2 a nd NLC is discussed. We compare the exact calculation with a ''naive'' approach to strong radiative corrections which has been widely used i n the literature. (C) 1998 Elsevier Science B.V. All rights reserved.
