  We briefly review recent results which we have obtained in the study of
J/psi+Z production at the LHC. Considering our NLO computation in the Colour
Evaporation Model (CEM) as an upper theory limit for the
single-parton-scattering contributions, we claim that the existing data set
from ATLAS points at a dominant double-parton-scattering contribution with an
effective cross section smaller than that for jet-related observables. As a
side product of our analysis, we have computed, for the first time, the
one-loop QCD corrections to the J/psi P_T-differential cross section in the
CEM.
