Abstract |
The decay is a singly Cabibbo-suppressed transition that involves the interference between and amplitudes, mediated by the exchange of a W boson at the tree level, that can generate CP asymmetries at the 1% level, even if the Cabibbo-Kobayashi-Maskawa phase is the only source of CP. Current experimental measurements of the CP asymmetry in decays are still limited by the statistical precision. In this work, the signal yield and corresponding raw asymmetry (Araw) for is measured using Belle II Monte Carlo (MC) samples at integrated luminosity of 1 ab^{−1}. The final goal of this analysis is to measure the CP asymmetry in , using as the reference mode, with (Belle + Belle II) dataset. |
