The ratio of cross-sections X(3872)/psi(2S) is also given, separately for prompt and non-prompt components, as well as the non-prompt fractions of X(3872) and psi(2S). Assuming independent single effective lifetimes for non-prompt X(3872) and psi(2S) production gives separating short- and long-lived contributions, assuming that the short-lived component is due to B (c) decays, gives R (B) = (3.57 +/- 0.33(stat) +/- 0.11(sys)) x 10(-2), with the fraction of non-prompt X(3872) produced via B (c) decays for p (T)(X(3872)) > 10 GeV being (25 +/- 13(stat) +/- 2(sys) +/- 5(spin)){\%}. The distributions of the dipion invariant mass in the X(3872) and psi(2S) decays are also measured and compared to theoretical predictions.", optnote="WOS:000394175000001", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=2971), last updated on Thu, 23 Mar 2017 12:06:12 +0000", issn="1029-8479", doi="10.1007/JHEP01(2017)117", opturl="http://arxiv.org/abs/1610.09303", opturl="https://doi.org/10.1007/JHEP01(2017)117", archivePrefix="arXiv", eprint="1610.09303", language="English" }
