abstract

We report the observation of a narrow state decaying into $J/\psi\pi^+\pi^-$ and produced in $220 pb^{-1}$ of $\bar{p} p $ collisions at $\sqrt{s}=1.96 TeV$ in the CDF II experiment. We observe $ 730 \pm 90 $ decays. The mass is measured to be $3871.3 \pm 0.7 (stat) \pm 0.4 (syst) MeV/c2$, with an observed width consistent with the detector resolution. This is in agreement with the recent observation by the Belle Collaboration of the X(3872) meson.

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

    hep-ph 2026-04 unverdicted novelty 5.5 of 10

    TQ4Q2.0 supplies the first complete, uncertainty-quantified set of NRQCD-based fragmentation functions for all-heavy tetraquarks, including nonconstituent channels and public grids for jet-associated production.

  2. Hidden-Charm Tetraquarks in a Mixture Model: Coupled-Channel Analysis with $c\bar{c}$ and Hadronic Molecular Components

    hep-ph 2025-05 conditional novelty 5.0 of 10

    A coupled-channel mixture model fitted to the X(3872) and Z(3930) masses predicts the X(3860) at about 3867 MeV, dominated by the charmonium core.

  3. Effect of a repulsive three-body interaction on the $DD^{(*)}K$ molecule

    nucl-th 2025-02 conditional novelty 5.0 of 10

    Repulsive three-body interactions gradually expand DD(∗)K molecules and eventually dissociate them into a D(∗)K bound pair plus a distant D meson.

  4. Probing the structure of $\chi_{c1}(3872)$: Heavy quark symmetries at work

    hep-ph 2026-06 unverdicted novelty 4.0 of 10

    Heavy-quark large-mass limit applied to E1 transitions of χ_c1(2P) yields decay rates that match LHCb measurements for χ_c1(3872) under the 2P assignment.

  5. Hadronic molecules

    hep-ph 2017-04 unverdicted novelty 2.0 of 10

    Hadronic molecules serve as a framework for certain exotic heavy-quark states where nonrelativistic effective field theories enable predictions with controlled uncertainty.
