Title: Observation of e + e - π + π - π 0 χ b 1 , 2 ( 1 P ) and search for e + e - Φ χ b 1 , 2 ( 1 P ) at s = 10.96 11.05 GeV

We report searches for the processes e + e - → π + π - π 0χ bJ and e + e - → Φχ bJ (J = 1,2) based on data samples collected by the Belle experiment at the KEKB collider. We report the first observation of the process e + e -- → ( π + π - π 0) non - ω χ b1 and first evidence for e + e - → ωχ bJ in the vicinity of the Υ(11020 ) resonance, with center-of-mass energies from 10.96 to 11.05 GeV. The significances for ( π + π - π 0 ) non - ω χ b 1 and ω χ b J are greater than 5.3 σ and 4.0 σ , respectively. We also investigate the energy dependence of the e + e -→ π + π - π 0 χ bJ cross section, but we cannot determine whether the contributions are from the Υ (10860) and Υ (11020) resonances or nonresonant continuum processes. The signals for e + e - → Φχ bJ are not significant, and the upper limits of the Born cross sections at the 90% confidence level are 0.7 and 1.0 pbmore » for e + e - → Φχ b1 and Φχ b2, respectively, for center-of-mass energies from 10.96 to 11.05 GeV.« less
