$f_{K} / f_{I ¨} $ in iso-symmetric QCD and the CKM matrix unitarity

Alessandro Conigli, Julien Frison, Alejandro SÃ¡ez

We present lattice results for $f_{K} / f_{I ¨} $ in the iso-symmetric limit of pure QCD (isoQCD) with $N_{f} = 2 + 1$ flavours, along with a determination of $∣ V_{u s} ∣/∣ V_{u d} ∣$ and a study on…

Hadronic physics from a Wilson fermion mixed-action approach: Setup and scale setting

Andrea Bussone, Alessandro Conigli, Julien Frison +6

We introduce a lattice QCD mixed action approach that employs Wilson-type quarks in the sea and valence sectors. The sea sector is based on gauge ensembles with $N_{f} = 2 + 1$ fla…
