Description

Ascribed as ρρ and K*K¯* molecular states, respectively, isoscalar f0(1500) and f0(1710) states are expected to have isovector partners, potentially identified as a0(1450) and a0(1710). The predicted dominant decay modes for these two a0 resonances are a0(1450)ωππ and a0(1710)ωππ,ϕππ. We estimate cross sections for two-photon production of these four resonances within hadronic molecular picture, and demonstrate that SuperKEKB's luminosity is sufficient for their observation and more precise parameter measurements.
