摘要：

3e discuss the process Z0→Vℓ+ℓ- which occurs dominantly through δ mixing. The branching ratio of this type of process is found to be as high as 10-5 for the light vector mesons, meaning that it should be detectable in the LEP experiment. We present expressions for the differential distribution of this decay, and we briefly comment on its significance as a potential background to the Higgs search. © 1990.
