abstract

We present a systematic study of twist-4 light-cone distribution amplitudes of the $K^*$ and $\phi$ meson in QCD. The structure of SU(3)-breaking corrections is studied in detail. Non-perturbative input parameters are estimated from QCD sum rules and a renormalon based model. As a by-product, we give a complete reanalysis of the parameters of the twist-4 $\rho$-meson distribution amplitudes.

Discussion (0). Continue with ORCID to comment.

  1. Pion Distribution Amplitudes from Functional QCD

    hep-ph 2026-07 conditional novelty 7.0 of 10

    The pion DA computed from functional QCD via LaMET has ⟨ξ²⟩_π = 0.267 (no quoted error), consistent with sum rules and DSE/BSE and 0.8σ below the lattice-LaMET value 0.300(41).

  2. Distribution amplitudes of heavy-light pseudo-scalar and vector mesons from Dyson-Schwinger equations framework

    hep-ph 2025-01 conditional novelty 6.0 of 10

    First DSE predictions for B*, B*_s, and B*_c distribution amplitudes show peaks near the Euclidean constituent quark mass ratio and a universal spin ordering.

  3. Non-perturbaitve effects for the isoscalar light vector $\omega$-meson in charmed meson semileptonic decays

    hep-ph 2025-11 conditional novelty 5.0 of 10

    With a new harmonic-oscillator model for the omega's transverse light-cone distribution amplitude, QCD light-cone sum rules reproduce the measured D+→ωℓν branching fractions and predict angular observables.

  4. Strong decay properties of P-wave single bottom baryons of the SU(3) flavor antitriplet $\bf\bar 3_F$

    hep-ph 2024-12 conditional novelty 5.0 of 10

    A systematic light-cone sum-rule calculation of strong decays for P-wave bottom baryons finds eight narrow states, matching several observed resonances.

  5. Vector mesons leading-twist longitudinal distribution amplitudes and related semi-leptonic decays within QCD sum rules

    hep-ph 2026-07 conditional novelty 4.0 of 10

    New QCD sum-rule calculation gives ξ-moments up to tenth order and PLP-model distribution amplitudes for ρ, K*, φ, which are then used to recalculate D_(s)→V semileptonic observables.

  6. Scrutinizing lepton flavor universality and transition form factor correlation from charmed meson semileptonic decay into light strange vector $K^*$ meson

    hep-ph 2026-07 conditional novelty 4.0 of 10

    A light-cone sum-rule calculation predicts D_s^+→K^{*0} form factors and a muon/electron branching ratio R=0.950, consistent with the Standard Model.
