Abstract

A new approach to the analysis of three body decays is presented. Measurements of the S-wave K{pi} amplitude are made in independent ranges of invariant mass from threshold up to the upper kinematic limit in D+ {yields} K-{pi}+{pi}+ decays. These are compared with results obtained from a fit where the S-wave is assumed to have {kappa} and K{sub 0}*(1430) resonances. Results are also compared with measurements of K-{pi}+ elastic scattering. Contributions from I = (1/2) and I = (3/2) are not resolved in this study. If I = (1/2) dominates, however, the Watson theorem prediction, that the phase behaviour below K{eta}' threshold should match that in elastic scattering, is not well supported by these data. Production of K-{pi}+ from these D decays is also studied.

Model-independent measurement of S-wave K{sup -}{pi}{sup +} systems using D{sup +}{yields}K{pi}{pi} decays from Fermilab E791

Aitala, E.M. ; Cremaldi, L.M. ; Gounder, K. ; ... - Physical Review. D, Particles Fields

A model-independent partial-wave analysis of the S-wave component of the K{pi} system from decays of D{sup +} mesons to the three-body K{sup -}{pi}{sup +}{pi}{sup +} final state is described. Data come from the Fermilab E791 experiment. Amplitude measurements are made independently for ranges of K{sup -}{pi}{sup +} invariant mass, and results are obtained below 825 MeV/c{sup 2}, where previous measurements exist only in two mass bins. This method of parametrizing a three-body decay amplitude represents a new approach to analyzing such decays. Though no model is required for the S-wave, a parametrization of the relatively well-known reference P- and D-waves,more »« less

S-wave K- pi+ system in D+ ---> K- pi+ pi+ decays from Fermilab E791

Meadows, B.T. ; /Cincinnati U.

A new approach to the analysis of three body decays is presented. Model-independent results are obtained for the S-wave K{pi} amplitude as a function of K{pi} invariant mass. These are compared with results from K{sup -}{pi}{sup +} elastic scattering, and the prediction of the Watson theorem, that the phase behavior be the same below K{eta}' threshold, is tested. Contributions from I = 1/2 and I = 3/2 are not resolved in this study. If I = 1/2 dominates, however, the Watson theorem does not describe these data well.
