Abstract

We perform numerical calculations of masses and decay constants of the lightest (flavoured) pseu- doscalar, vector and axialvector mesons in the (4) lattice gauge theory with three Dirac fermions in the antisymmetric representation. The corresponding continuum theory plays an important role in certa...
