| 英文摘要 | 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 root s = 13tev, corresponding to an integrated luminosity of 279 +/- 11 pb(-1). the 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. 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/psi pair are measured and compared to theoretical predictions. |
