The J/psi and gamma mesons are reconstructed in the mu(+)mu(-) decay mode and the signal yields are determined with a fit to the mu(+)mu(-) invariant mass distributions. The analysis is performed in the rapidity range 2.0 < y < 4.5 and transverse momentum range 0 < PT < 14 (15) GeV/c of the J/psi (gamma) mesons. The J/psi and gamma production cross-sections and the fraction of J/psi mesons from b-hadron decays are measured as a function of the meson P-T and y.", optnote="WOS:000321381800010", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=1536), last updated on Mon, 07 Oct 2013 11:14:28 +0000", issn="1029-8479", doi="10.1007/JHEP06(2013)064", opturl="http://arxiv.org/abs/1304.6977", opturl="https://doi.org/10.1007/JHEP06(2013)064", archivePrefix="arXiv", eprint="1304.6977", language="English" }
