Abstract:
Possible manifestations of the isospin-breaking mixing of the a00(980) and f0(980) resonances are analyzed in the D0→K0Sπ+π− and D0→K0Sηπ0 decays. It is shown that the a00(980)−f0(980) mixing has the most influence on the π+π− mass spectrum in the decay D0→K0Sπ+π−. Owing to the a00(980)−f0(980) mixing, the f0(980) peak in D0→K0Sf0(980)→K0Sπ+π− can experience distortions comparable with its size. The effect essentially depends on the relative phase between the amplitudes of the D0→K0Sf0(980) and D0→K0Sa00(980) transitions.
