Abstract: The e+e-??+?-?0?bJ (J=0,1,2) processes are studied using a 118fb-1 data sample acquired with the Belle detector at a center-of-mass energy of 10.867 GeV. Unambiguous ?+?-?0?bJ (J=1,2), ??b1 signals are observed, and indication for ??b2 is seen, both for the first time, and the corresponding cross section measurements are presented. No significant ?+?-?0?b0 or ??b0 signals are observed, and 90% confidence level upper limits on the cross sections for these two processes are obtained. In the ?+?-?0 invariant mass spectrum, significant non-? signals are also observed. We search for the X(3872)-like state (named Xb) decaying into ??(1S); no significant signal is observed with a mass between 10.55 and 10.65GeV/c2. � 2014 American Physical Society.
