We give a complete re-analysis of the leading twist quark-antiquark light-cone distribution amplitudes of longitudinal and transverse $\rho$ mesons. We derive Wandzura-Wilczek type relations between different distributions and update the coefficients in their conformal expansion using QCD sum rules including next-to-leading order radiative corrections. We find that the distribution amplitudes of quarks inside longitudinally and transversely polarized $\rho$ mesons have a similar shape, which is in contradiction to previous analyses.

  1. Exclusive photoproduction of a di-meson pair with large invariant mass

    hep-ph 2026-05 unverdicted novelty 7.0

    Calculations of di-meson photoproduction amplitudes at leading order show cross sections up to 100 times larger than single-meson cases, enabling better GPD extraction.

  2. Exclusive photoproduction of a di-meson pair with large invariant mass

    hep-ph 2026-05 unverdicted novelty 6.0

    Computes LO amplitudes for di-meson photoproduction channels sensitive to quark GPDs and reports high cross sections suitable for GPD studies at JLab energies.

  3. 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

    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.

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

    hep-ph 2026-07 conditional novelty 4.0

    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.
