Description
In scattering experiments, meson resonances have for many decades been studied in a 2-step procedure. First, the spin-density matrix has been non-parametrically extracted using the isobar model. From this, the resonance parameters have been determined in the second step. The latter requires detailed modeling of all amplitudes and thus could typically be performed simultaneously for few waves only and was restricted to a limited range of the spectral mass distribution. We will report on a new method that allows us to combine a parametric and non-parametric model in a single analysis step and that uses the information of the full mass spectrum. We successfully applied this method to a PWA model with over 336 partial waves.
