First measurement of the absolute branching fractions of nonleptonic decays and test of the rule
BESIII Collaboration, M. Ablikim, M. N. Achasov +689
The paper reports the first absolute measurements of the branching fractions for the Σ⁺ → p π⁰ and Σ⁺ → n π⁺ decays using BESIII J/ψ data, and tests the ΔI = 1/2 rule in Σ hyperon…
