  The differential cross-sections for processes of the type e+ e- to W+ W- to l
nu q anti-q are determined with account of background contributions and of
anomalous triple gauge boson couplings. Analytic expressions for dsigma/ds1 ds2
dcostheta, where theta is the production angle of the W boson, are numerically
integrated with the Fortran package GENTLE. QED corrections are taken into
account in the leading logarithmic approximation. The importance of the various
contributions is studied for center-of-mass energies of 190 GeV, 500 GeV, and 1
TeV.
