Determination of the CKM angle ϕ3 from a combination of Belle and Belle II results
Original language description
We report a determination of the CKM angle ϕ3, also known as γ, from acombination of measurements using samples of up to 711 fb-1 from the Belle experimentand up to 362 fb-1 from the Belle II experiment. We combine results from analyses ofB+ RIGHTWARDS ARROW DK+,B+ RIGHTWARDS ARROW Dπ+, and B+ RIGHTWARDS ARROW DASTERISK OPERATORK+ decays, where D is an admixture of D0 andD0 mesons, in a likelihood fit to obtain ϕ3 = (75.2 +- 7.6)°. We also briefly discuss theinterpretation of this result.
