Abstract

A Dalitz plot analysis of approximately 13 000 D(s)(+) decays to pi(+)pi(-)pi(+) has been performed. The analysis uses a 384 fb(-1) data sample recorded by the BABAR detector at the PEP-II asymmetric-energy e(+)e(-) storage ring running at center of mass energies near 10.6 GeV. Amplitudes and phases of the intermediate resonances which contribute to this final state are measured. A high precision measurement of the ratio of branching fractions is performed: B(D(s)(+)->pi(+)pi(-)pi(+))/B(D(s)(+)-> K(+)K(-)pi(+))=0.199 +/- 0.004 +/- 0.009. Using a model-independent partial wave analysis, the amplitude and phase of the S wave have been measured.
