Masses and decay constants of $D_{(s)}^{\ast }$ and $B_{(s)}^{\ast }$ mesons in Lattice QCD with $N_f=2+1+1$ twisted-mass fermions

V. Lubicz, A. Melis, S. Simula

We present a lattice calculation of the decay constants and masses of $D_{(s)}^{\ast }$ and $B_{(s)}^{\ast }$ mesons using the gauge configurations produced by the European Twisted Mass Collab…
