Using data from FOCUS (E831) experiment at Fermilab, we present a model independent partial-wave analysis of the K- π+ S-wave amplitude from the decay D+ → K- π+ π+. 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+ system.

Abstract

Using data from FOCUS (E831) experiment at Fermilab, we present a model independent partial-wave analysis of the K- π+ S-wave amplitude from the decay D+ → K- π+ π+. 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+ system.
