From strange to charmed baryons using two-flavour QCD

We compute the mass spectrum for strange and charmed baryons in the partially quenched approach using Nf=2 twisted mass QCD configurations. We investigate two main issues: the size of lattice artefacts using three values of the lattice spacing (the smallest of which is approximately 0.05 fm) and the dependence of baryon masses on meson masses. We thus perform a global fit in order to extrapolate simultaneously to the continuum limit and to the physical point. We obtain predictions for the Ωsss, Ξdss, Λuds, Ωccc, Ξdcc, Λudc masses.
