We show that the literature on pion exchange between charm and bottom mesons is inconsistent. We derive the formalism explicitly, expose differences between papers in the literature and clarify the implications. We show that the X(3872) can be a bound state but that results are very sensitive to a poorly constrained parameter. We confirm that bound states in the B Bbar sector are possible. The circumstances whereby exotic combinations can bind with cc or bb quantum numbers are explored.

  1. Molecular Interpretation of the $P_c(4440)$ and $P_c(4457)$ States

    hep-ph 2019-08 conditional novelty 7.0 of 10

    The paper predicts Pc(4440) has J^P = 3/2- and Pc(4457) has J^P = 1/2+ in a pion-exchange coupled-channel model without short-range terms.

  2. Constraining the $DDD^*$ three-body bound state via the $Z_c(3900)$ pole

    hep-ph 2024-12 conditional novelty 6.0 of 10

    A model-dependent study showing that the existence of a DDD* bound state is tied to the virtual-state pole position of Zc(3900), with binding occurring only for near-threshold Zc poles.

  3. Possibility of the antibottom-strange molecular pentaquarks near $ B\Sigma$ and $ B^*\Sigma$ thresholds

    hep-ph 2026-07 conditional novelty 5.0 of 10

    Coupled-channel OBE dynamics with S–D mixing produce three near-threshold poles dominated by BΣ/B*Σ that should show as narrow enhancements in open Bs0N, BΛ and B*Λ channels.

  4. Investigating triply heavy tetraquark states through QCD sum rules

    hep-ph 2024-12 conditional novelty 5.0 of 10

    QCD sum rules with condensates up to dimension 9 predict triply heavy tetraquark masses of 5.4 to 6.2 GeV for charm systems and 14.9 to 15.7 GeV for bottom systems.

  5. Heavy hadronic molecules with pion exchange and quark core couplings: a guide for practitioners

    hep-ph 2019-08 conditional novelty 5.0 of 10

    X(3872) is best described as a shallow D D* molecule in which one-pion exchange and a small charmonium core provide comparable attraction.

  6. Unquenched Charmonium and Beyond

    hep-ph 2026-02 conditional novelty 2.0 of 10

    This Lanzhou-group review argues that coupled-channel (unquenched) effects, not exotic constituents, are the common thread explaining charmonium anomalies from the rho-pi puzzle to the Y-problem states.
