We compute O(alpha_s) and O(alpha_s^n beta_0^{n-1}) (BLM) corrections to the five structure functions relevant for b->q l nu decays and apply the results to the moments of a few distributions of phenomenological importance. We present compact analytic one-loop formulae for the structure functions, with proper subtraction of the soft divergence.

Data determination of HQET parameters in inclusive charm decays
hep-ph 2025-02 conditional novelty 6.0 of 10

The first data-driven determination of the HQET parameters mu_pi^2, mu_G^2, rho_D^3 and rho_LS^3 for D0, D+ and Ds mesons is obtained from inclusive semileptonic decay widths and electron energy moments.
