Measurement of inclusive J/ψ pair production cross section in pp collisions at s =13 TeV
(2023) In Physical Review C 108(4).- Abstract
- The production cross section of inclusive J/ψ pairs in pp collisions at a center-of-mass energy s=13 TeV is measured with ALICE. The measurement is performed for J/ψ in the rapidity interval 2.50. The production cross section of inclusive J/ψ pairs is reported to be 10.3±2.3(stat.)±1.3(syst.) nb in this kinematic interval. The contribution from nonprompt J/ψ (i.e., originated from beauty-hadron decays) to the inclusive sample is evaluated. The effective double-parton scattering cross section is computed, neglecting the single-parton scattering contribution. © 2023 CERN.
