Abstract
The production cross-section of J/ψ pairs is measured using a data sample of pp collisions collected by the LHCb experiment at a centre-of-mass energy of √{s}=13 TeV, corresponding to an integrated luminosity of 279 ±11 pb-1. The measurement is performed for J/ψ mesons with a transverse momentum of less than 10 GeV/ c in the rapidity range 2 .0 < y < 4 .5. The production cross-section is measured to be 15 .2 ± 1 .0 ± 0 .9 nb. The first uncertainty is statistical, and the second is systematic. The differential cross-sections as functions of several kinematic variables of the J/ψ pair are measured and compared to theoretical predictions.
