Determination of the CKM angle <i>φ</i><sub>3</sub> from a combination of Belle and Belle II results
Description
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.
