Impact of gauge invariance on future e+e- data

Description

Recent data show that the Standard Electroweak model is a theory. Half a dozen of its predictions are tested to first order in their quantum corrections. This convincingly demonstrates that SU(2)XU(1) gauge invariance is no longer an 'assumption'. 'Meta-theories' beyond the standard model must abide by this symmetry, severely limiting the room for non-standard effects in future observables. I discuss the current strictures on the e+e- → W+W- differential cross-sections. Their direct measurement at LEP-2 is most unlikely to provide new information on the self-couplings of vector bosons.
