Description
I present recent precision results from lattice QCD regarding the masses of light quarks and neutral kaon mixing. These calculations were carried out directly at the physical point with full control over all systematic uncertainties. The masses of the u, d and s quarks are determined with an accuracy of a few percent while the neutral kaon mixing parameter B_K has an overall uncertainty of slightly over one percent. In particular, we find that m_u is more than 20 standard deviations away from 0 and that our standard model prediction for indirect CP violation in K->\pi\pi decays is in agreement with observation.
