Abstract
Starting from the meson-meson Green function in 3+1 dimensional quench ed lattice QCD we calculate potentials between heavy-light mesons for various light-quark mass parameters. For the valence quarks we employ the staggered scheme. The resulting potentials turn out to be short ra nged and attractive. A comparison with a tadpole improved action for t he gauge fields is presented.
