Upper limit for the cross-section of the overlapping scalar resonances F(0)(980) and A(0)(980) produced in proton proton collisions in the range of the reaction threshold
Upper limit for the cross-section of the overlapping scalar resonances F(0)(980) and A(0)(980) produced in proton proton collisions in the range of the reaction threshold
Utilizing a missing mass technique we investigate the pp --> ppX reaction scanning beam energies in the range permitting to create a mass close to that of the f(0) (980) and a(0) (980) scalar resonances, but still below the K+ K- threshold where they decay dominantly into pi pi and pi eta mesons,...

Utilizing a missing mass technique we investigate the pp --> ppX reaction scanning beam energies in the range permitting to create a mass close to that of the f(0) (980) and a(0) (980) scalar resonances, but still below the K+ K- threshold where they decay dominantly into pi pi and pi eta mesons, respectively. Prior to the data analysis we introduce a notion of the close to threshold total cross-section for broad resonances. We estimated for the overlapping mesons a(0) and f(0) the total cross-section to be smaller than 430 nb at excess energy of Q = 5 MeV. The experiment has been performed at the Cooler Synchrotron (COSY) using the COSY-11 facility. |
