AbstractAbstract
[en] We analyse the reaction e+e- → (Qanti Q) → μ+μ- on and around a heavy (Qanti Q) resonance. The cross section and asymmetries arising from γ-Z interference are shown to depend in a sensitive way on the electric charge and neutral current couplings of the quark Q. In the special case of toponium, we show that the reaction e+e- → (tanti t) → banti b will exhibit the unique phenomenon of γ-Z-W interference. Possibilities of neutrino counting on toponium are commented upon. (orig.)
