Lattice QCD

Lattice QCD is playing a crucial role in precision tests of the Standard Model by predicting hadronic matrix elements (decay constants, form factors, ...) model-independently. After providing an overview of what can be expected from state-of-the-art lattice QCD computations (and also, what can not yet be expected), I will provide examples for how experiment and theory work hand in hand towards over-constraining SM parameters, concentrating on Quark Flavour Physics. I will close with an overview of new challenges and opportunities.
