Abstract

Recent lattice calculations on the interaction energy of two heavy-light mesons (Q2q2) in SU(3) are interpreted in terms of the potential for the corresponding single heavy-light meson (Qq). This model supports earlier work, with four static quarks Q4 in SU(2), that there is a large overestimate of the binding compared with the lattice data---unless the basic Qq potentials are modified by a four-quark form factor.
