Description

The double-differential cross sections of the promptly-produced J/psi mesons,in transverse momentum, p_T, and absolute rapidity, |y|, are measured in pp collisions at sqrt{s} = 13 TeV, using a dimuonsample collected by CMS in 2015, corresponding to an integrated luminosity of 2.4 fb-1. The results are based on a two-dimensional analysis of the dimuon invariant mass and decay length, and cover a broad p_T range, extending from 20 to 120 GeV, in the |y|<1.2 window.
