Abstract
The Standard Model predicts interference effects between [Formula: see text] and [Formula: see text] boson exchange in fermion pair production which cause a forward–backward asymmetry [Formula: see text] even for energies well below the [Formula: see text]–pole. This energy–dependent asymmetry ([Formula: see text] at 10.58[Formula: see text]GeV) is proportional to the SM [Formula: see text] parameter and can be measured at the Belle and Belle[Formula: see text]II experiments. The sensitivity to New Physics as well as theoretical and experimental challenges are described.
