Inclusive study of bottomonium production in association with an $��$ meson in $e^+e^-$ annihilations near $��(5S)$

We study bottomonium production in association with an $��$ meson in $e^+e^-$ annihilations near the $��(5S)$, at a center of mass energy of $\sqrt{s}=10.866\,$GeV. The results are based on the $121.4\,$fb$^{-1}$ data sample collected by the Belle experiment at the asymmetric energy KEKB collider. Only the $��$ meson is reconstructed and the missing-mass spectrum of $��$ candidates is investigated. We observe the $e^+e^-\to����_J(1D)$ process and find evidence for the $e^+e^-\to����(2S)$ process, while no significant signals of $��(1S)$, $h_b(1P)$, nor $h_b(2P)$ are found. Cross sections for the studied processes are reported.
