Abstract (data abstract)
CERN-LHC. Inclusive J/$\psi$ production is studied in minimum-bias proton-proton collisions at a centre-of-mass energy of $\sqrt{s} = 5.02$ TeV by ALICE at the CERN LHC. The measurement is performed at mid-rapidity ($|y| < 0.9$) in the dielectron decay channel down to zero transverse momentum $p_{\rm T}$, using a data sample corresponding to an integrated luminosity of $19.4 \pm 0.4 $ nb$^{-1}$. The measured $p_{\rm T}$-integrated inclusive J/$\psi$ production cross section is $\text{d}\sigma/\text{d}y = 5.64 \pm 0.22 (\text{stat.}) \pm 0.33 (\text{syst.}) \pm 0.12 (\text{lumi.})$ $\mu$b. The $p_{\rm T}$-differential cross section $\text{d}^2\sigma/\text{d}p_{\rm T}\text{d}y$ is measured in the $p_{\rm T}$ range 0$-$10 GeV/$c$ and compared with state-of-the-art perturbative QCD calculations. The J/$\psi$ $\langle p_{\rm T} \rangle$ and $\langle p_{\rm T}^2 \rangle$ are extracted and compared with results obtained at other collision energies.
