Abstract

We report the preliminary measurement of the CP asymmetry of the D⁰ → K⁰_S K⁰_S decay, which is consistent with no CP violation and improves the uncertainty with respect to the previous measurement of this quantity by more than a factor of three. Also, the expected precision on CP asymmetry of the D⁰ → K⁰_S K⁰_S decay by the Belle II experiment is presented.
