"Review of Neutral Kaon Oscillations in and beyond the Standard Model from Lattice QCD"

Presented by Anastassios Vladikas, INFN Roma Tor Vergata

Wednesday, May 16, 2018, 2:00 pm — Small Seminar Room, Bldg. 510

The study of the low energy strong interaction effects in neutral K-meson oscillations is based on the lattice regularisation of QCD. Precise and consistent results for the bag parameter BK, in line with expectations from Standard Model flavour phenomenology, have been obtained over the years, from several variants of lattice QCD. More recently, a few groups have also studied BK in extensions of the Standard Model. The discrepancies seen between certain results from different groups are arguably attributed to uncontrolled systematic errors in the non-perturbative renormalisation and running of weak matrix elements. The Schroedinger Functional renormalisation scheme may help resolve these discrepancies.
