The measurements are carried out through the e(+)e(-) decay channel at midrapidity (vertical bar y vertical bar < 0.9) in the transverse momentum region 1.5 < p(T) < 10 GeV/c. Both prompt and non-prompt J/psi measurements indicate a significant suppression for p(T) > 5 GeV/c, which becomes stronger with increasing collision centrality. The results are consistent with similar LHC measurements in the overlapping pT intervals, and cover the kinematic region down to p(T) = 1.5 GeV/c at midrapidity, not accessible by other LHC experiments. The suppression of prompt J/psi in central and semicentral collisions exhibits a decreasing trend towards lower transverse momentum, described within uncertainties by models implementing J/psi production from recombination of c and (c) over bar quarks produced independently in different partonic scatterings. At high transverse momentum, transport models including quarkonium dissociation are able to describe the suppression for prompt J/psi. For non-prompt J/psi, the suppression predicted by models including both collisional and radiative processes for the computation of the beauty-quark energy loss inside the quark-gluon plasma is consistent with measurements within uncertainties.
