# Phenomenological Estimate of the Binding Energy of Heavy Dimesons

@article{Janc2000PhenomenologicalEO, title={Phenomenological Estimate of the Binding Energy of Heavy Dimesons}, author={D. Janc and Mitja Rosina}, journal={Few-Body Systems}, year={2000}, volume={31}, pages={1-11} }

Abstract. A phenomenological estimate is derived such that the binding energies of dimesons are expressed as combinations of masses of different mesons and baryons. The estimate is almost model-independent, the only major assumptions being that the wave functions of the two light quarks in Λc, Λb and in the and dimesons are very similar, and that for heavy quarks the QQ interaction is half as strong as the interaction. We get (I = 0, J = 1) bound by about 100 MeV and unbound.

It is shown why NP-hardness still holds when this subproblem Steiner trees is omitted by considering (highly) connected networks only and focussing on the satisfaction of the flow constraints, and how much effort in computation and implementation is really necessary to solve realistic scenarios in practice.
