Contribution

It offers new preliminary results on meson masses, decay constants, and light-quark masses in $N_f=2+1+1$ QCD using Wilson-clover twisted mass fermions on multiple lattice spacings.

Findings

Meson masses and decay constants are computed at various lattice spacings.

Preliminary light-quark renormalized mass is estimated.

Configurations include physical pion point on large lattices.

Abstract

We present a preliminary study of the pion, kaon and D-meson masses and decay constants in isosymmetric QCD, as well as a preliminary result for the light-quark renormalized mass. The analysis is based on the gauge ensembles produced by ETMC with $N_f=2+1+1$ flavours of Wilson-clover twisted mass quarks, spanning a range of lattice spacings from $\sim0.10$ to $0.07$ fm and include configurations at the physical pion point on lattices with linear size up to $L~\sim~5.6$~fm
