Flavor Physics and Lattice QCD

摘要

Our ability to resolve new physics effects is, largely, limited by theprecision with which we calculate. The calculation of observables in theStandard (or a new physics) Model requires knowledge of associated hadroniccontributions. The precision of such calculations, and therefore our ability toleverage experiment, is typically limited by hadronic uncertainties. The onlyfirst-principles method for calculating the nonperturbative, hadroniccontributions is lattice QCD. Modern lattice calculations have controllederrors, are systematically improvable, and in some cases, are pushing thesub-percent level of precision. I outline the role played by, highlight stateof the art efforts in, and discuss possible future directions of latticecalculations in flavor physics.
