Quark Flavor Physics Review Aida X. El-Khadra

I review the status of lattice-QCD calculations relevant to quark flavor physics. The recent avail-ability of physical-mass ensembles with large physical volumes generated by a growing number of lattice collaborations is an exciting development and I discuss their impact on the landscape of lattice flavor physics calculations. The activities of the newly formed FLAG-2 collaboration which provides averages of quantities calculated in lattice QCD that are relevant for quark fla-vor physics are also discussed. My talk covers (a subset of) the same quantities reviewed by FLAG-2, including results for K, D(s), and B(s) meson decay constants and semileptonic decay form factors, as well as for hadronic matrix elements of neutral (K, D, and B(s)) meson mixing. I also briefly discuss recent progress towards understanding nonleptonic K decay and long-distance contributions to ∆mK
