| Abstract: | We report on partial results of the analysis of a p?p backward elastic scattering experiment, between 175 and 750 MeV/c. Various evidences are given of the resonant nature of a backward peak at the S-meson mass. Analysis leads to JPC=4++, firmly connected to other experimental data with IG=1?. All results agree for an assignment to the A2 trajectory. |
