Precision flavour physics is a powerful tool to test the Standard Model and search for new physics beyond the TeV scale. In this talk, I will discuss recent progress in lattice QCD calculations of long-distance hadronic effects relevant to flavour phenomenology, focusing on two research directions.

The first direction concerns electromagnetic corrections to weak decay amplitudes, including leptonic meson decays, inclusive hadronic tau decays, and possible extensions to semileptonic processes. These corrections are crucial for the precise extraction of CKM matrix elements from experimental decay rates. The second addresses long-distance contributions to neutral D-meson mixing, through the calculation of absorptive and dispersive amplitudes involving intermediate hadronic states. This programme provides first-principles input for observables of direct phenomenological interest, with potential implications for studies of CP violation in the charm sector and possible extensions to the kaon sector.
