Abstract
Meson and baryon masses in the light (u,d and s) sector are calculated using tadpole-improved gauge field and fermion actions. These are cor rected to order O(alpha(2)) on the classical level using next-nearest- neighbour terms. The results, obtained at lattice spacings of 0.4 and 0.27 fm, are compared to Wilson action calculations.
