Adiabaticity and color mixing in tetraquark spectroscopy

Abstract

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. © 2013 American Physical Society.
