The dataset corresponds to an integrated luminosity of 0.37 fb{sup -1} collected with the LHCb detector. The measurement is presented as a function of transverse momentum, p{sub T}, and rapidity, y, of the J/{psi} meson, in the kinematic region 2 Available from: http://dx.doi.org/10.1140/epjc/s10052-013-2631-3 Germany 2013-11-15 English Journal Article Journal Name: European Physical Journal.
