- W2010396876 abstract "Abstract It is well known that the ϱ meson appears narrower in measurements of the pion form factor, F π ( s ), than in ππ phase-shift analyses of OPE reactions. We show that this discrepancy is a consequence of neglecting the inelastic part of the pion form factor, F π in ( s ). A simple one-parameter ansatz for F π in ( s ) removes the discrepancy completely. As parameter we choose an effective inelastic scattering length, a in , at a fixed inelastic threshold, s in = (0.919 GeV) 2 . A fit to ∥ F π ( s )∥ 2 data yields a in = 0.002 μ −3 as well as ω-ϱ interference parameters Γ ( ω → 2 π )/ Γ ω = (3.7 ± 1.4)%, φ = 92° ± 9°. As input for the elastic part of F π ( s ) we use the ππ phase shift δ ( s ) and η ( s ). This fit also yields the parameter values to a compilation of δ ( s ) and η ( s ). This fit also yields the parameter values m ϱ = (776.3 ± 0.4) MeV, Γ ϱ = (154.5 ± 1.0) MeV, m ϱ ′ = 1635 ± 6) MeV, Γ ϱ ′ = (173 ± 24) MeV, ππ scattering length a 1 = (0.040 ± 0.001) μ −3 , and ϱ ′ elasticity x = 0.23 ± 0.06." @default.
