BESIII extracts branching fractions for ψ(3686)→p p-bar π⁰ and ψ(3686)→p p-bar η (two solutions each) and measures the N(1535) width ratio Γ(Nη)/Γ(Nπ) = 0.99 ± 0.05 ± 0.19 from partial-wave fits.
The integrated luminosity is measured using Bhabha scattering events, with an uncertainty less than 1.0% [ 42]
