Description

The cross sections for the reaction e+e-→l anti lq anti q and for similar four fermion production processes at LEP 1, LEP 2 and the NLC are calculated. Due to the extraordinary symmetry properties of the process, very compact analytical formulae describe the double differential distributions in the invariant masses of the l anti l and q anti q pairs. The total cross sections may be obtained with two numerical integrations. (orig.)
