### Event details

A calculation of the kaon mixing parameter B_K using unquenched mixed-action lattice QCD is presented along with a complete systematic error budget. The calculation was performed at two lattice spacings and uses non-perturbative matching.

The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
