Coupled Channel Analysis of the Pp-Annihilation Into

The three pseudoscalar meson final states of pp-annihilation at rest, 0 0 0 , 0 0 j and 0 jj have been studied together with scattering data. These channels have shown to be suitable to extract information on the I = 0 and I = 1 S- and D-waves. In particular the existence of two I G (J PC ) = 0 + (0 ++ ) resonances was reported in a previous analysis using a N/D inspired method. The aim of the analysis presented here is to quantify the compatibility of the data samples with respect to the resonance hypotheses of the applied partial waves. To apply consequently the K-matrix formalism for the production process within the Isobar model for the I = 0 S-wave a 3 \Theta 3 K-matrix had to be used. 1 Coupled channel analysis All three data samples, 0 0 0 , 0 0 j and 0 jj have been studied in the spirit of the Isobar model using the K--matrix formalism [1, 2, 3]. The final state interaction of pp-annihilation at rest into three mesons is considere..
