abstract

In this work, we introduce the hadronic loop contribution to explain the anomalous radiative transitions between $h_b(nP)$ and $\eta_b(mS)$, which was recently observed by the Belle Collaboration. Our calculation shows that the hadronic loop mechanism associated with these known decay mechanisms can explain why there exist anomalous radiative transitions between $h_b(nP)$ and $\eta_b(mS)$. This study deepens our understanding of the decay mechanism of higher bottomonium radiative decays.

  1. Medium modifications of $1P$-wave charmonia $\chi_{cJ}(1P)$ in cold nuclear matter

    hep-ph 2025-10 conditional novelty 6.0 of 10

    χcJ(1P) masses drop by 34–97 MeV in nuclear matter in the QMC+unquenched-loop model, with the D*D̄* loop dominating χc2 and no D-D̄ threshold crossing below 3ρ0.

  2. Two-body Hidden Charm Decays of $D$ Wave Charmonia

    hep-ph 2025-01 conditional novelty 6.0 of 10

    Using a meson-loop model calibrated to psi(3770) to J/psi eta, the paper predicts Gamma(psi2(3823) to J/psi eta) = 29.6 keV and smaller eta_c omega and psi3(3842) rates.

  3. Discovery potential of charmonium $2P$ states through the $e^+e^- \to \gamma D\bar{D}$ processes

    hep-ph 2024-12 conditional novelty 5.0 of 10

    Using the measured e+e- -> gamma X(3872) cross section as a reference, the authors predict measurable e+e- -> gamma chi_c0(2P) and e+e- -> gamma chi_c2(2P) production and propose the gamma D Dbar final state as a sear...

  4. 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.
