Precision Measurement of - Mass Difference
BESIII Collaboration, M. Ablikim, M. N. Achasov +684
The paper reports a precise measurement of the mass difference between the charm-strange mesons D_s*+ and D_s+ using e⁺e⁻ collision data collected by the BESIII detector.

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…
