Study of ${\rm Y}(10753)$ decays to ${\pi }^{+}{\pi }^{-}{\rm Y}(nS)$ final states at Belle II

Belle II Collaboration, I. Adachi, L. Aggarwal +393

We present an analysis of the process $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}{\rm Y}(nS)$ (where $n$ = 1, 2, or 3) reconstructed in $19.6$ $\mathrm{f}{\mathrm{b}}^{-1}$ of Belle II data during a special run of the…
