Abstract:
Using the Belle data on the decay Υ(10860)→Υ(1S)f0(980)→Υ(1S)π+π−, we estimate the fraction of the process Υ(10860)→Υ(1S)f0(980)→Υ(1S)ηπ0, 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. With an instantaneous luminosity of 8×1035 cm−2⋅s−1 at the SuperKEKB collider, one can collect with the Belle II detector about a hundred Υ(10860)→Υ(1S)ηπ0 events in the narrow region of the ηπ0 invariant mass near the K¯K thresholds in a time roughly spent on the present Belle experiment.
