We report a determination of the CKM angle phi_3, also known as gamma, from a combination of measurements using samples of up to 711 fb^(-1) from the Belle experiment and up to 362 fb^-1 from the Belle II experiment. We combine results from analyses of B+-> DK+, B+-> D pi(+), and B+-> D*K+ decays, where D is an admixture of D0 and D0 mesons, in a likelihood fit to obtain phi_3 = (75.2 +/- 7.6)degrees. We also briefly discuss the interpretation of this result.

Abstract
We report a determination of the CKM angle phi_3, also known as gamma, from a combination of measurements using samples of up to 711 fb^(-1) from the Belle experiment and up to 362 fb^-1 from the Belle II experiment. We combine results from analyses of B+-> DK+, B+-> D pi(+), and B+-> D*K+ decays, where D is an admixture of D0 and D0 mesons, in a likelihood fit to obtain phi_3 = (75.2 +/- 7.6)degrees. We also briefly discuss the interpretation of this result.File in questo prodotto:
