Light and strange quark masses with $N_{f} = 2 + 1$ Wilson fermions

Gregorio Herdoíza, Fernando P. Panadero, Carlos Pena +1

We report on the status of an update of our collaboration's previous computation of light and strange quark masses in QCD with $N_{f} = 2 + 1$ dynamical flavours. Bare quark masses are…

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

Alessandro Conigli, Julien Frison, Alejandro Sáez

We present lattice results for $f_{K} / f_{π}$ 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 t…

Primordial Black Holes as Dark Matter and the Tachyonic Trap During Inflation

Yuma S. Furuta, Mindaugas Karčiauskas, Kazunori Kohri +1

We show that resonant processes during multi-field inflation can generate a large curvature perturbation on small scales. This perturbation naturally leads to the formation of prim…
