Description
The computation of observables from inclusive hadronic processes is widely regarded as a challenging task from the lattice QCD perspective. However, the access to such observables at the non-perturbative level is crucial, especially in Flavour Physics, where high-precision comparisons of first-principles theoretical predictions and experimental measurements could reveal discrepancies, potentially pointing to New Physics Scenarios beyond the Standard Model. A viable practical solution is provided by the Hansen-Lupo-Tantalo reconstruction method from Euclidean lattice correlation functions. Two recent applications of this method include the hadronic decays of the $\tau$ lepton, allowing for the extraction of the $V_\mathrm{us}$ and $V_\mathrm{ud}$ CKM matrix elements, and the semi-leptonic decay of the charmed $D_s$ meson. Alongside a discussion of the methodology, we illustrate results for both the applications.
