OFF-SHELL W PAIR PRODUCTION IN E(-) ANNIHILATION - THE CC11 PROCESS()E()

The various four-fermion production channels in e(+)e(-) annihilation are discussed and the CC11 process e(+)e(-) --> (f) over bar(1)(u)f(1) (d)f(2)(u) (f) over bar(2)(d), f not equal e is studied in detail. The cross section d(2) sigma/ds(1)ds(2), with s(1), s(2) being the invari ant masses squared of the two fermion pairs, may be expressed by six g eneric functions. All but one may be found in the literature. The cros s section, including initial-state radiation and the Coulomb correctio n, is discussed and compared with other calculations from low energies up to root s = 2 TeV.
