We search for the decay mode Y(3S) -> pi(+)pi(-) h(b)(1P) and find no evidence for the bottomonium spin-singlet state h(b)(1P) in the invariant mass distribution recoiling against the pi(+)pi(-) system. Assuming the h(b)(1P) mass to be 9.900 GeV/c(2), we measure the upper limit on the branching fraction B[Y(3S) -> pi(+)pi(-) h(b)(1P)] < 1.2 x 10(-4), at 90{\%} confidence level. We also investigate the chi(bJ)(2P) -> pi(+)pi(-) chi(bJ)(1P), Y(3S) -> pi(+)pi(-) Y(2S), and Y(2S) -> pi(+)pi(-) Y(1) dipion transitions and present an improved measurement of the branching fraction of the Y(3S) -> pi(+)pi(-) Y(2S) decay and of the Y(3S) -- Y(2S) mass difference.", optnote="WOS:000293182000001", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=710), last updated on Sat, 13 Aug 2011 13:15:39 +0000", issn="1550-7998", doi="10.1103/PhysRevD.84.011104", opturl="http://arxiv.org/abs/1105.4234", opturl="https://doi.org/10.1103/PhysRevD.84.011104", archivePrefix="arXiv", eprint="1105.4234", language="English" }
