Description

The 0- and 1- meson masses are calculated in SU(2) lattice gauge theory at β = 2.3 with Wilson fermions on a 104 lattice. The calculation is based on a 32sup(nd) order hopping parameter expansion. The fermion determinant can be taken into account for quark masses heavier than proportional 600 MeV. For lighter quarks only an estimate is given due to the limitations of statistics. (orig.)
