Abstract
Based on an collision data sample corresponding to an integrated luminosity of collected with the BESIII detector at , the first amplitude analysis of the singly Cabibbo-suppressed decay is performed. From the amplitude analysis, the component is found to be dominant with a fraction of , where the first uncertainty is statistical and the second systematic. In combination with the absolute branching fraction measured by BESIII, we obtain , where the third uncertainty is due to the branching fraction . The precision of this result is significantly improved compared to the previous measurement. This result also differs from most of theoretical predictions by about , which may help to improve the understanding of the dynamics behind.File | Dimensione | Formato | |
