Adiabaticity and color mixing in tetraquark spectroscopy    [PDF]

Javier Vijande, Alfredo Valcarce, Jean-Marc Richard

We revisit the role of color mixing in the quark-model calculation of tetraquark states, and compare simple pairwise potentials to more elaborate string models with three- and four-body forces. We attempt to disentangle the improved dynamics of confinement from the approximations made in the treatment of the internal color degrees of freedom.
