abstract

Using a newly developed interquark potential, we tabulate values of the radial Schr\"{o}dinger wave function or its first nonvanishing derivative at zero quark--antiquark separation, for $c\bar{c}$, $c\bar{b}$, and $b\bar{b}$ levels that lie below, or just above, the flavor threshold. These quantities are required inputs for evaluating quarkonium production cross sections.

  1. Radiative decays $J/\psi,\,\psi(2S)\rightarrow\gamma\eta^{(\prime)}$ in perturbative QCD with relativistic corrections

    hep-ph 2026-07 conditional novelty 6.0 of 10

    Order-q² relativistic corrections in pQCD roughly double J/ψ→γη(') rates and favor a smaller mixing angle, while ψ(2S) rates overshoot data and may require coherent ηc mixing.

  2. Impact of relativistic corrections to high-pT prompt-psi(2S) production at hadron colliders

    hep-ph 2025-10 conditional novelty 6.0 of 10

    Relativistic O(v^2) corrections to color-singlet fragmentation functions, especially for gluons, bring leading-power NRQCD predictions for prompt psi(2S) at high pT into agreement with LHC data without color-octet mat...

  3. Tree-level NLO corrections to inclusive $\psi'$ production in High Energy Factorization

    hep-ph 2025-09 conditional novelty 6.0 of 10

    Including tree-level NLO corrections in kT-factorized NRQCD improves the global description of inclusive psi(2S) production at the LHC, with A0 TMD gluons describing the full measured range.

  4. Relativistic corrections to exclusive photoproduction of Quarkonia near-threshold

    hep-ph 2025-06 conditional novelty 6.0 of 10

    The leading relativistic correction to near-threshold photoproduction of J/psi and Upsilon is derived; for J/psi it is so large that the standard moment-expansion analysis of the proton's gluon gravitational form fact...

  5. Precision Study of Semileptonic and Non-Leptonic $B_c$ Decays to $\eta_c$ and P Wave Charmonia

    hep-ph 2026-07 conditional novelty 5.0 of 10

    Data-constrained NRQCD form factors yield R(χ_c0)=0.185(3), R(χ_c1)=0.147(26), R(h_c)=0.068(2) and related B_c branching fractions for P-wave charmonia.

  6. NNLO QCD Corrections to $D$-Wave Spin-Singlet Heavy Quarkonia Decay $\eta_{Q2}\to\gamma\gamma$ via the Principle of Maximum Conformality

    hep-ph 2026-06 unverdicted novelty 5.0 of 10

    NNLO perturbative calculation with PMC scale setting for η_c2 and η_b2 → γγ decay widths and branching ratios in NRQCD effective theory.

  7. Bayesian Inferring Nucleon's Gravitation Form Factors via Near-threshold $J/\psi$ Photoproduction

    hep-ph 2025-01 conditional novelty 5.0 of 10

    A Bayesian NLO analysis of near-threshold J/psi photoproduction data, combined with lattice QCD, finds compatible proton gravitational form factors and prefers negative C_q and C_g.
