Using a large sample of <Formula Not Shown> decays collected by the FOCUS photoproduction experiment at Fermilab, we present the first non-parametric analysis of the <Formula Not Shown> amplitudes in <Formula Not Shown> decay. The technique is similar to the technique used for our non-parametric measurements of the <Formula Not Shown> form factors. Although these results are in rough agreement with those of E687, we observe a wider S-wave contribution for the <Formula Not Shown> 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 <Formula Not Shown> mass.

Abstract

Using a large sample of decays collected by the FOCUS photoproduction experiment at Fermilab, we present the first non-parametric analysis of the amplitudes in decay. The technique is similar to the technique used for our non-parametric measurements of the form factors. Although these results are in rough agreement with those of E687, we observe a wider S-wave contribution for the 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 mass.
