Abstract:
Using the data on the decay D+s→f0(980)π+→K+K−π+, we estimate the amplitude of the process D+s→[f0(980)→(K+K−+K0¯K0)→a00(980)]π+→ηπ0π+, caused by the mixing of a00(980) and f0(980) resonances that breaks the isotopic invariance due to the K+ and K0 meson mass difference. Effects of the interference of this amplitude with the amplitudes of the main mechanisms responsible for the decay D+s→ηπ0π+ are analyzed. As such mechanisms, we examine the transition D+s→ηρ+→ηπ0π+, which is observed in experiment, and the possible transition D+s→(a00(980)π++a+0(980)π0)→ηπ0π+. It is shown that the rapidly varying phase of the a00(980)−f0(980) transition amplitude strongly influences the interference curves.
