Abstract

Using data from FOCUS (E831) experiment at Fermilab, we present a model independent partial-wave analysis of the K−π+K^-\pi^+ S-wave amplitude from the decay D+→K−π+π+D^+ \to K^-\pi^+\pi^+. The S-wave is a generic complex function to be determined directly from the data fit. The P- and D-waves are parameterized by a sum of Breit-Wigner amplitudes. The measurement of the S-wave amplitude covers the whole elastic range of the K−π+K^-\pi^+ system.
