B-meson light-cone distribution amplitudes are discussed in these lectures in the framework of HQET. The evolution equation for the leading-twist distribution amplitude is derived in one-loop approximation. QCD sum rules for distribution amplitudes are discussed.

  1. Unified Description of Pseudoscalar Meson Structure from Light to Heavy Quarks

    hep-ph 2026-02 unverdicted novelty 5.0

    An algebraic light-front model supplies unified leading-twist PDAs, LFWFs, GPDs, PDFs, EFFs, charge radii and IPS-GPDs for light, heavy-light and heavy-heavy pseudoscalar mesons from the same Bethe-Salpeter amplitudes.
