Abstract

The potential between two heavy-light mesons as a function of the heavy quark separation is calculated in quenched SU(3) lattice QCD. We study the case of heavy-light mesons with a static heavy quark and light quarks of mass close to the strange quark mass. We explore the case of light quarks with the same and with different flavors, classified according to the light quark isospin. We evaluate the appropriate light quark exchange contributions and explore the spin dependence of the interaction. Comparison is made with meson exchange.
