Abstract
Using a large sample of D+ → K- K+ π+ decays collected by the FOCUS photoproduction experiment at Fermilab, we present the first non-parametric analysis of the K- π+ amplitudes in D+ → K- K+ π+ decay. The technique is similar to the technique used for our non-parametric measurements of the D+ → over(K, ̄)* 0 e+ ν form factors. Although these results are in rough agreement with those of E687, we observe a wider S-wave contribution for the over(K, ̄)0* 0 (1430) contribution than the PDG [W.-M. Yao, et al., J. Phys. G 33 (2006) 1], world average mass and width. We have some weaker evidence for the existence of a new, D-wave component at low values of the K- π+ mass. © 2007 Elsevier B.V. All rights reserved.
