Measurement of the $e^+e^-\to K^0_{\scriptscriptstyle S}K^\pm\pi^{\mp}\pi^0$ and $K^0_{\scriptscriptstyle S}K^\pm\pi^\mp\eta$ cross sections using initial-state radiation

The processes $e^{+} e^{-} \to K_{S}^{0} K^{\pm} π^{\mp} π^{0}$ and $e^{+} e^{-} \to K_{S}^{0} K^{\pm} π^{\mp} η$ are studied over a continuum of energies from threshold to 4 GeV with the initial-state photon radiation method. Using 454 fb $^{- 1}$ data collected with the BABAR detector at the SLAC PEP-II storage ring, the first measurements of the cross sections for these processes are obtained. The intermediate resonance structures from $K^{* 0} (K π)^{0}$ , $K^{*} (892)^{\pm} (K π)^{\mp}$ and $K^0_{\scriptscriptstyle S}K^\pm\rho^{\mp} $a r e s t u d i e d . T h e$ J/\psi$ is observed in all of these channels, and corresponding branching fractions are measured.
