In particular, we perform a study of the quark mass dependence of the chiral condensate \$\Sigma\$ and topological susceptibility \$\chi\_top\$ in the range \$270 MeV < m\_\pi < 500 MeV\$ and compare our data with analytical predictions. In addition, we compute \$\chi\_top in the quenched approximation where we match the lattice spacing to the \$N\_f=2+1+1\$ dynamical simulations. Using the Kaon, \$\eta\$ and \$\eta^\prime\$ meson masses computed on the \$N\_f=2+1+1\$ ensembles, we then perform a preliminary test of the Witten-Veneziano relation.
