英文摘要The e(+)e(-) -> pi(+)pi(-) pi(0)chi(bj) ( J = 0, 1, 2) processes are studied using a 118 fb(-1) data sample acquired with the Belle detector at a center-of-mass energy of 10.867 GeV. Unambiguous pi(+)pi(-) pi(0)chi(bj) ( J = 1, 2), omega chi(b1) signals are observed, and indication for omega chi(b2) is seen, both for the first time, and the corresponding cross section measurements are presented. No significant pi(+)pi(-) pi(0)chi(b0) or omega chi(b0) signals are 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 (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).
