The production cross-section of $J/\\psi$ pairs is measured using a data sample of $pp$ collisions collected by the LHCb experiment at a centre-of-mass energy of $\\sqrt{s} = 13$ TeV, corresponding to an integrated luminosity of $279 \\pm 11 {\\mathrm{pb^{-1}}}$. \nThe measurement is performed for $J/\\psi$ mesons with a transverse momentum of less than 10 GeV$/c$ in the rapidity range $2.0<y<4.5$. \nThe production cross-section is measured to be $15.2 \\pm 1.0 \\pm 0.9$ nb. \nThe first uncertainty is statistical, and the second is systematic. \nThe differential cross-sections as functions of several kinematic variables of the $J/\\psi$ pair are measured and compared to theoretical predictions.\nIn the differential cross-section distributions only the statistical uncertainties are shown as the systematic ones are\nnegligibly small and almost 100% correlated.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.79484.v1/t1","@type":"Dataset","description":"Differential cross-section of
