First measurement of the absolute branching fractions of $I^£^{+}$ nonleptonic decays and test of the $I^ I = 1/2$ 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…
