Description
We investigate η-η' mixing in infrared regularized U(3) chiral perturbation theory by calculating the η and η' masses up to one-loop order. From this analysis it becomes obvious that even at leading order η-η'-mixing does not obey the usually assumed one-mixing-angle scheme if large Nc counting rules are not employed. (orig.)
