The D-0 mesons are required to originate from semimuonic decays of B- and (B) over bar (0)mesons. These decays are partially reconstructed in a data set of proton-proton collisions at center-of-mass energies of 7 and 8 TeV collected with the LHCb experiment and corresponding to an integrated luminosity of 3 fb(-1). The y c p parameter is measured to be (0.57 +/- 0.13(stat) +/- 0.09(syst)){\%}, in agreement with, and as precise as, the current world-average value.", optnote="WOS:000455164600004", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=3870), last updated on Sun, 20 Jan 2019 15:14:43 +0000", issn="0031-9007", doi="10.1103/PhysRevLett.122.011802", opturl="http://arxiv.org/abs/1810.06874", opturl="https://doi.org/10.1103/PhysRevLett.122.011802", archivePrefix="arXiv", eprint="1810.06874", language="English" }
