Abstract(summary):

The mass difference between the K+ and K-0 mesons induces mixing of the a(0)(0)(980) and f(0)(980) resonances. The mixing amplitude is large, on the order of m(K)(m(K)(2)(0) - m(K)(2)(+))(1/2) approximate to rootalpham(K)(2) near the K (K) over bar thresholds, and its phase changes sharply by 90degrees. A high-energy experiment on the pi(-)p --> etapi(0)n reaction in a polarized target is proposed. In this experiment, the presence of a(0)(0)(980)-f(0)(980) mixing can be unambiguously and simply identified by the presence of a large jump in the azimuthal asymmetry of the cross section for production of the etapi(0) system in the S wave near the K (K) over bar thresholds. Our estimates of the magnitude of the polarization effect, which is expected to be observed in the experiment, are almost model-independent. (C) 2004 MAIK "Nauka / Interperiodica".
