abstract

We compute the contributions of dimension six two-quark operators to the non-leptonic decay width of heavy hadrons due to the flavor changing bottom-to-up-quark transition in the heavy quark expansion. Analytical expressions for the Darwin term $\rho_D$ and the spin-orbit term $\rho_{\rm LS}$ are obtained with leading order accuracy.

  1. $B$-meson decay width up to $1/m_b^3$ corrections within and beyond the Standard Model

    hep-ph 2025-12 conditional novelty 7.0 of 10

    Complete analytic HQE matching coefficients for B-meson decay widths up to 1/m_b^3 are derived for generic new-physics operators, including previously missing weak-annihilation terms.

  2. Total decay rates of $B$ mesons at NNLO-QCD

    hep-ph 2024-12 conditional novelty 7.0 of 10

    At NNLO in QCD, the heavy quark expansion predicts the B+, Bd, and Bs decay widths and semileptonic branching fractions within experimental uncertainties, with a systematic 4% shortfall in the central width values.

  3. Predictions for $b$-baryon lifetimes at NNLO-QCD

    hep-ph 2026-07 accept novelty 6.0 of 10

    NNLO-QCD corrections to the free b-quark decay and NLO corrections to dimension-five operators reduce uncertainties in HQE predictions for b-baryon lifetimes, yielding excellent agreement with experiment.
