The compilation of e⁺e^- → hadrons total cross section data

Notation:

Observables:

• σ: total cross section corrected by the authors as indicated in the 'Radiative corrections' column
• R: hadronic R-ratio = σ(e⁺e^- → hadrons, Born) / σ(e⁺e^- → μ⁺μ^-, Born)
• |F_π|²: pion form-factor squared (see, e.g., the CMD-3 paper)

Radiative corrections applied to the measured cross section in the original publication:

• ISR -- correction for the initial state radiation and the e⁺e^- vertex loops
• e,μ VP -- correction for electron and muon 1-loop contributions to the photon vacuum polarisation operator, typically applied in pre-1990 papers (see G. Bonneau, F. Martin, Nucl. Phys.B 27, 381 (1971))
• VP -- correction for the full photon vacuum polarisation operator (i.e. including leptons and hadrons, presumably to 1-loop)

The 'weight' column contains a multiplicative factor to be applied to the cross section in order to account for FSR and/or estimate contributions of unmeasured channels using symmetry relations, so that the sum of weighted cross sections will approximate the total hadronic cross section. The latter can be used to compute hadronic vacuum polarisation using a dispersion relation. Particularly, this compilation was used in Phys. Part. Nucl. 55, 1432 (2024) to estimate the leading order hadronic contribution to (g_μ-2) (see also this talk).

As π+ π- π0 in K+ K- π+ π- π0 is dominated by ω contribution, we find σ(K K π+ π- π0) + σ(K K π0 γ) ~= 2 σ(K+ K- π+ π- π0) * (1 + Br(ω --> π0 γ) / Br(ω --> 3pi)) ~= 2.19 σ(K+ K- π+ π- π0).
