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 Nf=2+1+1 flavours of Wilson-clover twisted mass quarks, spanning a range of lattice spacings from ∼0.10 to 0.07 fm and include configurations at the physical pion point on lattices with linear size up to L ∼ 5.6~fm
