Light quark physics from lattice QCD

Abstract

I review lattice calculations of quantities that involve light quarks, including light quark masses, the vector form factor f_+(0) needed for semileptonic kaon decays, and kaon mixing. Results for most of these quantities are now available from multiple groups. Averages of these results are presented, along with a discussion of the methodology behind the averaging procedure. Recent progress in calculations of K->pi pi matrix elements is also reviewed.
