Abstract
The increasing importance of hadronic resonances in our understanding of the Standard Model is underscored by recent advancements in lattice Quantum Chromodynamics (QCD) calculations. We review recent developments, with a particular emphasis on electroweak transitions that result in two-hadron final states. Additionally, we present the finite-volume lattice QCD methodologies that are pivotal in such studies in the context of preliminary results from the .
