Quark Flavor Physics Review

Understand

I review the status of lattice-QCD calculations relevant to quark flavor physics.

• The recent availability 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 flavor 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.
