Kaon oscillations in the Standard Model and Beyond using Nf=2 dynamical quarks

Understand

We compute non-perturbatively the B-parameters of the complete basis of four-fermion operators needed to study the Kaon oscillations in the SM and in its supersymmetric extension.

• We perform numerical simulations with two dynamical maximally twisted sea quarks at three values of the lattice spacing on configurations generated by the ETMC.
• Unwanted operator mixings and O(a) discretization effects are removed by discretizing the valence quarks with a suitable Osterwalder-Seiler variant of the Twisted Mass action.
• Operators are renormalized non-perturbatively in the RI/MOM scheme.
