Perspectives of a precise measurement of the charge asymmetry in muon pair production at Belle Ⅱ

Forward-backward asymmetry in the muon pairs production in electron-positron annihilation is caused by the interference of the photon and Z-boson already at leading order. A high precise measurement of the value of this asymmetry, A_FB, at the Super B-factory will provide stringent limitations on the New Physics effects. Even though A_FB≈0.01 at 10 GeV center-of-mass energy of B-factory operation, a huge statistics expected at the BelleⅡ experiment will provide an opportunity to obtain high precision. This report briefly describes perspectives as well as obstacles on the way to achieve the precise results.
