On the 1g^2 corrections to hadron masses - Hoek, J.; Smit, J. (Elsevier)
The strong coupling limit of lattice QCD is reviewed and the important corrections of order 1g^2 to the pion, rho, nucleon and delta masses are computed with Wilson's fermion method. The nucleon-delta mass difference is obtained by decomposing the baryon field into independent fields transforming in irreducible representations of the rotation-flavor group.
