摘要：

We study the potentialities for exposing physics beyond the standard model that are offered by accurate measurements of the process Z --> bbBAR in a high luminosity phase at LEP. In particular we propose a strategy by defining observables in such a way that they are separately sensitive to different kinds of New Physics. This approach enables us to show that with 10(7)-10(8) produced Z from analysis of bbBAR pairs one may either obtain very stringent bounds on the extra neutral gauge bosons sector, or identify it unambiguously. Also, it appears that Z --> bbBAR provides under those circumstances a privileged tool to reveal clean virtual effects of supersymmetry.
