Measurements of $e^{+} e^{-} \to K^{+} K^{-} η$ , $K^{+} K^{-} π^{0}$ , and $K_{s}^{0} K^{\pm} π^{\mp}$ cross sections using initial state radiation events

This paper reports measurements of processes:

e^{+} e^{-} \to γ K_{S}^{0} K^{\pm} π^{\mp}

e^{+} e^{-} \to γ K^{+} K^{-} π^{0}

e^{+} e^{-} \to γ ϕ η

, and

e^{+} e^{-} \to γ ϕ π^{0}

. The initial-state radiated photon allows to cover the hadronic final state in the energy range from thresholds up to

\approx 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_{S}^{0} K^{\pm} π^{\mp}

final state, moduli, and relative phase of the isoscalar and the isovector components of the

e^{+} e^{-} \to K K^{*} (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^{-} \to K_{S}^{0} K^{\pm} π^{\mp}

K^{+} K^{-} π^{0}

ϕ η

final states. The cross section for the OZI-forbidden process

e^{+} e^{-} \to ϕ π^{0}

, and the

J / ψ

branching fractions to

K K^{*} (892)

and

K^{+} K^{-} η

are also measured.
