The data were recorded by the CMS experiment and correspond to an integrated luminosity of 4.8 fb(−1). The measurements are performed in a kinematic range in which the X(3872) candidates have a transverse momentum 10 < p (T)  < 50 GeV and rapidity |y| < 1.2. The ratio of the X(3872) and ψ(2S) cross sections times their branching fractions into J/ψπ(+)π(−) is measured as a function of p T. In addition, the fraction of X(3872) originating from B decays is determined. From these measurements the prompt X(3872) differential cross section times branching fraction as a function of p T is extracted. The π(+)π(−) mass spectrum of the J/ψπ(+)π(−) system in the X(3872) decays is also investigated.Hadron-Hadron ScatteringArticle10.1007/JHEP04(2013)154https://orcid.org/0000-0002-3932-3769openAccess
