dc.description.abstract We report on the inclusive J/psi production cross section measured at the CERN Large Hadron Collider in proton-proton collisions at a center-of-mass energy root s = 13 TeV. The J/psi mesons are reconstructed in the e(+)e(-) decay channel and the measurements are performed at midrapidity (vertical bar y vertical bar < 0.9) in the transverse-momentum interval 0 < p(T) < 40 GeV/c, using a minimum-bias data sample corresponding to an integrated luminosity L-i(nt) = 32.2 nb(-1) and an Electromagnetic Calorimeter triggered data sample with L-i(nt) = 8.3 pb(-1). The p(T)-integrated J/psi production cross section at midrapidity, computed using the minimumbias data sample, is d sigma/dy vertical bar(y) =0 = 8.97 +/- 0.24 (stat) 0.48 (syst) +/- 0.15 (lumi) mu b. An approximate logarithmic dependence with the collision energy is suggested by these results and available world data, in agreement with model predictions. The integrated and p(T)-differential measurements are compared with measurements in pp collisions at lower energies and with several recent phenomenological calculations based on the non-relativistic QCD and Color Evaporation models. en
