abstract

The production cross section of inclusive J/$\psi$ pairs in pp collisions at a centre-of-mass energy $\sqrt{s} = 13$ TeV is measured with ALICE. The measurement is performed for J/$\psi$ in the rapidity interval $2.5 < y < 4.0$ and for transverse momentum $p_{\rm T} > 0$. The production cross section of inclusive J/$\psi$ pairs is reported to be $10.3 \pm 2.3 {\rm (stat.)} \pm 1.3 {\rm (syst.)}$ nb in this kinematic interval. The contribution from non-prompt J/$\psi$ (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.

  1. Probing Heavy-Quark Spin Symmetry in Double $J/\psi$ Hadroproduction

    hep-ph 2026-08 conditional novelty 8.0 of 10

    A complete O(alpha_s^5) NRQCD calculation for prompt J/psi pair hadroproduction finds LHC data fix one combination of color-octet LDMEs, yielding a set that tests heavy-quark spin symmetry via eta_c data.

  2. Momentum fraction and hard scale dependence of double parton scattering in heavy-ion collisions

    hep-ph 2026-03 conditional novelty 6.0 of 10

    Model predicts final-state-dependent DPS effective cross sections in pPb and PbPb collisions, potentially turning heavy-ion DPS into a probe of transverse hadron and nuclear structure.
