Title: Measurement of the I = 1 / 2 K π S -wave amplitude from Dalitz plot analyses of η c K K ¯ π in two-photon interactions

Here we study the processes γγ→K$$0\atop{S}$$K ±π and γγ→K +K -π 0 using a data sample of 519 fb -1 recorded with the BABAR detector operating at the SLAC PEP-II asymmetric-energy e +e - collider at center-of-mass energies at and near the Υ(nS) (n=2, 3, 4) resonances. We observe ηc decays to both final states and perform Dalitz plot analyses using a model-independent partial wave analysis technique. This allows a model-independent measurement of the mass-dependence of the I=1/2 Kπ S-wave amplitude and phase. A comparison between the present measurement and those from previous experiments indicates similar behavior for the phase up to a mass of 1.5 GeV/c 2. In contrast, the amplitudes show very marked differences. Lastly, the data require the presence of a new a 0(1950) resonance with parameters m=1931±14±22 MeV/c 2 and Γ=271±22±29 MeV.
