# The neutral kaon mixing parameter from lattice QCD

#### The neutral kaon mixing parameter from lattice QCD

- Event time: 2:00pm
- Event date: 31st March 2010
- Speaker: Jack Laiho (University of Glasgow)
- Location: Lecture Theatre B, James Clerk Maxwell Building (JCMB) James Clerk Maxwell Building Peter Guthrie Tait Road Edinburgh EH9 3FD GB

### 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.

### About Particle Physics Theory seminars

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..
