Hadronic Molecules in Lattice QCD

Abstract

An adiabatic approximation is used to derive the binding potential between two heavy-light mesons in quenched SU(2)-colour lattice QCD. Analysis of the meson-meson system shows that the potential is attractive at short- and medium-range. The numerical data is consistent with the Yukawa model of pion exchange
