Hadron-hadron and hadron-hadron-hadron properties from lattice QCD

While lattice QCD is able to compute single-hadron properties to few- percent accuracy, only very recently has it become possible to extract precise information about the interactions among hadrons. First I will review the methodology for extracting scattering information from lattice correlation functions in a finite volume. Then I will discuss recent progress in computing a variety of hadron-hadron and multi-hadron correlation functions using lattice QCD. This will include recent efforts to learn about the simplest nuclear systems.
