“…As an example, for the CLEO data used in this paper, the energy spread varies due to different accelerator lattices [30]: one (for CLEO III detector) with a single wiggler magnet and a center-of-mass energy spread ∆=1.5 MeV, the other (for CLEO-c detector) with the first half of its full complement (12) of wiggler magnets and ∆=2.3 MeV [12]. The two ∆'s lead to two maximum total cross sections 635 nb and 441 nb, respectively, which differ prominently from BESII value of 717 nb for ∆ = 1.3 MeV [31]. All these subtle effects must be taken into account in data analysis.…”

With the recent measurements of ψ ′ and J/ψ decay into octet-baryon pairs, we study the relative phase between the strong and the electromagnetic amplitudes, and find a large phase by fitting the present data. The fits take into account the details of experimental effects, including energy spread and initial state radiation. We also predict some branching fractions of ψ ′ decays and the continuum production rates at the J/ψ mass based on the relative phase and absolute amplitudes obtained from the fits.

“…Information about basic properties of the ψ(2S ) other than mass and total width is scarce: there are only a few measurements of Γ e + e − [31][32][33][34] with an average of 2.37 ± 0.04 keV [35] and indirect estimates of the leptonic branching fractions B(e + e − ) = (78.2 ± 1.7) · 10 −4 and B(μ + μ − ) = (78 ± 9) · 10 −4 [35] based on the values of Γ e + e − and total width [36,37].…”
