## Abstract

We present a refined calculation of the eta-prime mass using staggered fermions and Wuppertal smeared operators. We use quenched and dynamical configurations of size 16^3x32 with Nf=0, Nf=2 and Nf=4, and compare our results with the expected forms from quenched, partially quenched and unquenched chiral perturbation thoery.
