Event details
Several tensions between experimental measurements and the Standard Model have been reported, at least in the quark-flavor sector. Should these discrepancies mature into significant discrepancies, they would be evidence for new physics. In this talk, I discuss several lattice-QCD calculations (from the Fermilab Lattice and MILC Collaborations) that go into the Standard-Model predictions for flavor-changing neutral currents: particle-antiparticle mixing in $B$ and $B_s$ mesons and semileptonic $B$ decays mediated (in the SM) by penguins.

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..
