Summary
This paper reports measurements of processes: e⁺e⁻ → γK°{sub s}K{sup ±}π{sup ±}, e⁺e⁻ → γK⁺K⁻π°, e⁺e⁻ → γφη and e⁺e⁻ → γφπ°. The initial state radiated photon allows to cover the hadronic final state in the energy range from thresholds up to ≈ 4.6 GeV. The overall size of the data sample analyzed is 232 fb⁻¹, collected by the BABAR detector running at the PEP-II e⁺e⁻ storage ring. From the Dalitz plot analysis of the K°{sub s}K{sup ±}π{sup ±} final state, moduli and relative phase of the isoscalar and the isovector components of the e⁺e⁻ → KK*(892) cross section are determined. Parameters of φ and ρ recurrences are also measured, using a global fitting procedure which exploits the interconnection among amplitudes, moduli and phases of the e⁺e⁻ →K°{sub s}K{sup ±}π{sup ±}, K⁺K⁻π°, φη final states. The cross section for the OZI-forbidden process e⁺e⁻ → φπ° and the J/ψ branching fractions to KK*(892) and K⁺K⁻η are also measured.
