Constructing hybrid baryons with flux tubes - art. no. 111501

Hybrid baryon states are described in quark potential models as having expl icit excitation of the gluon degrees of freedom. Such states are described in a model motivated by the strong coupling limit of Hamiltonian lattice ga uge theory, where three flux tubes meeting at a junction play the role of t he glue. The adiabatic approximation for the quark motion is used, and the flux tubes and junction are modeled by beads which are attracted to each ot her and the quarks by a linear potential, and vibrate in various string mod es. Quantum numbers and estimates of the energies of the lightest hybrid ba ryons are provided. [S0556-2821(99)50221-X].
