The ratio of the two branching fractions is ℬ(D*⁰ → D⁰π⁰) / ℬ(D*⁰ → D⁰γ) = 1.90 ± 0.07 ± 0.05, which is independent of the assumption made above. The first uncertainties are statistical and the second ones systematic. The precision is improved by a factor of 3 compared to the present world average values.©2015 American Physical SocietyBranching fractions (Nuclear physics)D MesonsUncertaintyMesons--DecayArticleAblikim, M., M.
