The article is devoted to double J/psi-meson production at LHC. Theoretical predictions for pp -> 2J/psi+X cross section at sqrt{s}=7 TeV for different kinematical restrictions are presented. Special attention is payed to possible contribution of novel particles -- tetraquarks build from four c-quarks. According to presented in our article estimates, it is quietly possible to observe at least one of these state (tensor meson) experimentally.

  1. Two photon decay width of the fully charmed tetraquarks: revisiting prospects for ultraperipheral collisions

    hep-ph 2026-05 conditional novelty 5.0

    Using recent four-body quark model wave functions and NRQCD, the authors compute two-photon couplings and UPC cross sections for fully charmed tetraquarks, showing resonant terms exceed continuum in J/ψJ/ψ but not in ...

  2. All-charm tetraquarks at hadron colliders: A high-precision fragmentation perspective

    hep-ph 2026-04 unverdicted novelty 5.0

    The authors construct and publicly release the TQ4Q2.0 fragmentation functions for all-heavy S-wave tetraquarks via NRQCD factorization, extending prior work with nonconstituent contributions and replica-based uncertainties.

  3. Prompt ${J/\psi}$-pair production at the LHC: impact of loop-induced contributions and of the colour-octet mechanism

    hep-ph 2019-06 unverdicted novelty 5.0

    Loop-induced CS and selected CO SPS contributions to prompt J/ψ pairs are too small or kinematically limited to account for LHC data or affect DPS control regions.

  4. Two photon decay width of the fully charmed tetraquarks: revisiting prospects for ultraperipheral collisions

    hep-ph 2026-05 unverdicted novelty 4.0

    Computes two-photon couplings of scalar and tensor fully-charmed tetraquarks via NRQCD from recent four-body wave functions and finds resonant terms dominate J/ψJ/ψ but not diphoton production in UPCs, disagreeing wit...
