      abstract     = {We report searches for the processes
                      $e^+e^-\to\pi^+\pi^-\pi^0\chi_{bJ}$ and
                      $e^+e^-\to\phi\chi_{bJ}$ (J=1,2) in the vicinity of the
                      $\Upsilon(11020)$ resonance using energy scan data collected
                      by the Belle experiment at the KEKB collider. We observe
                      $e^+e^-\to \pi^+\pi^-\pi^0\chi_{b1}$ and find evidence for
                      $e^+e^-\to \omega\chi_{b2}$ processes for data with
                      center-of-mass energies from 10.96 to 11.05~GeV for the
                      first time. The statistical significance for
                      $\pi^+\pi^-\pi^0\chi_{b1}$ and $\omega\chi_{b2}$ are
                      $6.1\sigma$ and $4.0\sigma$, respectively. We investigate
                      energy dependence of the $e^+e^-\to\pi^+\pi^-\pi^0\chi_{bJ}$
                      cross section and find that it is consistent with production
                      of $\Upsilon(10860)$ and $\Upsilon(11020)$ resonances
                      without significant non-resonant contribution. Assuming
                      $e^+e^-\to \pi^+\pi^-\pi^0\chi_{bJ}$ proceeds via
                      $\Upsilon(10860)$ and $\Upsilon(11020)$, the branching
                      fraction
                      $\mathcal{B}(\Upsilon(11020)\to\pi^+\pi^-\pi^0\chi_{bJ})=(8.6\pm4.1\pm6.1^{+4.5}_{-2.5})\times10^{-3}$
                      is measured for the first time, where the first error is
                      statistical, the second is systematic, and the third from
                      the branching fraction of $\Upsilon(11020)\to e^+e^-$. The
                      signals for $e^+e^-\to \phi\chi_{bJ}$ are not significant,
                      and the upper limits of the Born cross sections at the 90\\%
                      confidence level are $0.6$ and $1.0$~pb for $e^+e^-\to
                      \phi\chi_{b1}$ and $\phi\chi_{b2}$, respectively, for
                      center-of-mass energies from 10.96 to 11.05~GeV.},
