Measurements of e+e- → K+K-η, K+K-π0, and Ks0K±π∓ cross sections using initial state radiation events

This paper reports measurements of processes: e(+)e(-)->gamma(KSK +/-)-K-0 pi(-/+), e(+)e(-)->gamma K+K-pi(0), e(+)e(-)->gamma phi eta, and e(+)e(-)->gamma phi pi(0). The initial-state radiated photon allows to cover the hadronic final state in the energy range from thresholds up to approximate 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 (KSK +/-)-K-0 pi(-/+) 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 phi and rho recurrences are also measured, using a global fitting procedure which exploits the interconnection among amplitudes, moduli, and phases of the e(+)e(-)->(KSK +/-)-K-0 pi(-/+), K+K-pi(0), phi eta final states. The cross section for the OZI-forbidden process e(+)e(-)->phi pi(0), and the J/psi branching fractions to KK*(892) and K+K-eta are also measured.
