Abstract

In this article I provide an overview of the current state of scattering within lattice QCD, along with ongoing projects that examine weak decays involving scattering states as either final or intermediate states. Significant progress has been made in the study of multi-hadron weak decays, opening the door for scattering calculations to make meaningful contributions to flavour physics and further establishing lattice QCD as the key non-perturbative tool for QCD predictions. In addition to discussing new calculations, I also highlight recent advancements in finite-volume formalisms, which enable the exploration of previously inaccessible channels.
