Study of $e^{+}{e}^{-}\to h^{+}{h}^{-}J/\psi (h=\pi ,K,p)$ via initial-state radiation at Belle~II

Belle II Collaboration, M. Abumusabh, I. Adachi +417

Using a data sample of 427.9 fb${}^{-1}$ collected by the Belle~II detector at or near the ${\rm Y}(4S)$ and ${\rm Y}(10753)$ resonances, the cross sections for $e^{+}{e}^{-}\to h^{+}{h}^{-}J/\psi$ $(h=\pi /K/p)$…
