Abstract
In this proceeding contribution we report on a test of the famousWitten-Veneziano formula using lattice techniques. We perform dedicated quenched simulations and apply the spectral projector method to determine the topological susceptibility in pure Yang-Mills theory. In order to compute the relevant meson masses and the flavor singlet decay constant we employ lattice QCD with Nf = 2+1+1 dynamical Wilson twisted mass fermions. Taking the continuum and the SU(2) chiral limits we find good agreement within uncertainties for both sides of the formula.
