Potential observation of the ${\rm Y}(6S)\to {\rm Y}(1^3{D}_J)\eta$ transitions at Belle II

Abstract

We perform the investigation of two-body hidden-bottom transitions of the ${\rm Y}(6S)$, which include ${\rm Y}(6S)\to {\rm Y}(1^3{D}_J)\eta (J=1,2,3)$ decays. For estimating the branching ratios of these processes, we consider contributions from the triangle hadronic loops composed of S-wave $B_{(s)}$ and $B_{(s)}^{\ast }$ mesons, which are a bridge to connect the ${\rm Y}(6S)$ and final states. Our results show that both of the branching ratios of these decays can reach $10^{-3}$. Due to such considerable potential to observe these two-body hidden-bottom transitions of the ${\rm Y}(6S)$, we suggest the forthcoming Belle II experiment to explore them.
