Description
Whether one is interested in measuring transition matrix elements or extracting scattering parameters, a common requirement is to constrain and determine an analytical expression for the scattering amplitude. A systematically improvable, well developed theoretical method is to determine the finite volume spectrum using lattice QCD and connect it to the infinite volume scattering amplitude through the Luescher formalism. In the present talk I will review current investigations that follow this approach for the study of mesonic and baryonic systems with two and three hadrons.
