We compute the masses, decay constants and gluonic matrix elements of the
η and η′ mesons in lattice simulations across four lattice spacings with
the light quark masses reaching down to the physical point. A comparison
is made to Large-Nc chiral perturbation theory (ChPT) predictions
and the NLO low energy constants are determined.
