Stability of multiquarks in a simple string model

J Vijande, A Valcarce, JM Richard - Physical Review D—Particles, Fields …, 2007 - APS
A simple string model inspired by the strong-coupling regime of quantum chromodynamics
is used as a potential for studying the spectrum of multiquark systems with two quarks and
two antiquarks, with a careful treatment of the four-body problem. It is found that the ground
state is stable, lying below the threshold for dissociation into two isolated mesons.
