Measurement of Born Cross Sections for at GeV and Observation of
BESIII Collaboration, M. Ablikim, M. N. Achasov +771
Using 44.55 fb of collision data collected by the BESIII detector at the BEPCII collider, we report the first measurement of the Born cross sections for the $e^+e^-…

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…
