Abstract
Energies of four-quark systems have been extracted in a static quenche d SU(2) lattice Monte Carlo calculation for six different geometries, both planar and non-planar, with beta = 2.4 and lattice size 16(3) x 3 2. In all cases, it is found that the binding energy is greatly enhanc ed when the four quarks can be partitioned in two ways with comparable energies. Also it is shown that the energies of the four-quark states cannot be understood simply in terms of two-quark potentials.
