Abstract |
We propose a simultaneous analysis of and decays to measure model-independent observables for the determination of . The decays is partially reconstructed, removing systematic uncertainty on from the soft-pion reconstruction. By assuming equality of the semileptonic decay width of and mesons, we can also measure , the ratio of the branching fractions of the decaying into charged and neutral pairs. From the model-independent observables, and the form-factor parameters of both decays can be determined a-posteriori assuming any form-factor model and lattice data inputs. Using simulation, we present the potential of this analysis with the current Belle II dataset. |
