Using the decay chain Y(2S) -> pi(+)pi Y-(1S), Y(1S) -> D*X-+/-, where X is unobserved, we measure the branching fraction B[Y(1S) -> D*X-+/-] = (2.52 +/- 0.13(stat) +/- 0.15(syst){\%} and the D*(+/-) momentum distribution in the rest frame of the Y(1S). We find evidence for an excess of D*+/- production over the expected rate from the virtual photon annihilation process Y(1S) -> gamma* -> c (c) over bar -> D*X-+/-.", optnote="ISI:000274002800002", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=502), last updated on Tue, 22 Mar 2011 14:41:57 +0000", issn="1550-7998", doi="10.1103/PhysRevD.81.011102", opturl="http://arxiv.org/abs/0911.2024", opturl="https://doi.org/10.1103/PhysRevD.81.011102", archivePrefix="arXiv", eprint="0911.2024", language="English" }
