Description
Inclusive non-leptonic $B$-meson decays provide a key testing ground for the Standard Model (SM) and for searches for new physics in the flavour sector. In the framework of the Heavy Quark Expansion (HQE), decay widths are expressed in powers of $1/m_b$, where subleading terms become increasingly important as experimental precision improves.
In this talk, I present recent progress toward a more precise theoretical description of inclusive non-leptonic B-meson decays. This includes the computation of dimension-7 two-quark operators corrections in the SM and dimension-6 Darwin-term contributions arising both from SM QCD-penguin operators and from general BSM four-quark operators. I discuss the structure of these subleading contributions and their relevance for achieving a more precise and consistent description of inclusive $B$-meson decays in and beyond the SM.
