Dalitz plot analysis of D_s^+ → K^+K^-π^+


We perform a Dalitz plot analysis of about 100 000 D_s^+ decays to K^+K^-π^+ and measure the complex amplitudes of the intermediate resonances which contribute to this decay mode. We also measure the relative branching fractions of D_s^+→K^+K^+π^- and D_s^+→K^+K^+K^-. For this analysis we use a 384 fb^(-1) data sample, recorded by the BABAR detector at the PEP-II asymmetric-energy e^+e^- collider running at center-of-mass energies near 10.58 GeV.
