Nonperturbative QCD calculations of hadronic matrix elements are needed to understand the structure of the matter in our universe and to search for physics beyond the Standard Model. Numerical lattice gauge theory is uniquely suited for this task and has reached a remarkable level of precision. Traditionally, lattice QCD determinations of hadronic matrix elements were restricted to situations with at most one stable hadron in the initial and final states, and with a single insertion of a local current. However, recent years have seen significant progress in calculating more complicated observables. More...
