Non Abelian Gauge Couplings in Four Fermion Processes at LEP
  The LEP data on four fermion processes are presently used to study the non abelian gauge couplings of the Standard Model. The present theoretical error for two classes of processes, single-W production and radiative four fermion final states, is discussed according to the results of the four fermion working group of the LEP2 Monte Carlo Workshop held at CERN.
