Description
We present a complete analysis of the forward-backward asymmetry as well as of the longitudinal polarization of the outgoing lepton in the processes e+e- → l+l-, around the energy of a vector meson resonance (UPSILON, T...). Both effects manifest a strong energy-dependent structure near the mass of the resonance due to the interference with the background. These observables are carefully studied near the UPSILON peak. Furthermore, the effects of possible vector mesons of higher mass, below and above the Z0, are also considered. (orig.)
