Abstract / Description:The $e^+e^- \\to \\pi^+ \\pi^- \\pi^0 \\chi_{bJ}$ ($J=0,~1,~2$) processes are studied using a 118~fb$^{-1}$ data sample collected at a center-of-mass energy of 10.867 GeV, in the $\\Upsilon(10860)$ energy range, with the Belle detector. The $\\pi^+ \\pi^- \\pi^0 \\chi_{b1}$, $\\pi^+\\pi^-\\pi^0\\chi_{b2}$, $\\omega\\chi_{b1}$ signals and the evidence of $\\omega\\chi_{b2}$ are observed for the first time and the cross sections are measured. No significant $\\pi^+\\pi^-\\pi^0\\chi_{b0}$ or $\\omega\\chi_{b0}$ signal is observed and 90\\% confidence level upper limits on the cross sections for these two processes are obtained. In the $\\pi^+\\pi^-\\pi^0$ invariant mass spectrum, significant non-$\\omega$ signals are also observed. We search for the $X(3872)$-like state with a hidden $b\\bar{b}$ component (named $X_b$) decaying into $\\omega \\Upsilon(1S)$; no significant signal is observed with a mass between $10.55$ and $10.65$ GeV/$c^2$.
