We report a determination of the CKM angle ϕ3, also known as γ, 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+ → Dπ+, and B+ → D∗K+ decays, where D is an admixture of D0 and D0 mesons, in a likelihood fit to obtain ϕ3 = (75.2 ± 7.6)◦.

Abstract

We report a determination of the CKM angle ϕ3, also known as γ, 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+ → Dπ+, and B+ → D∗K+ decays, where D is an admixture of D0 and D0 mesons, in a likelihood fit to obtain ϕ3 = (75.2 ± 7.6)◦. We also briefly discuss the interpretation of this result.
