Determining the sign of the Z-penguin amplitude
We point out that the precision measurements of the pseudo observables Rb0, Ab, and AFB0,b performed at the CERN LEP and the Stanford Linear Collider suggest that in models with minimal-flavor violation the sign of the Z-penguin amplitude is identical to the one present in the standard model. We det...
