(HYBRID) BARYONS: SYMMETRIES AND MASSES

We construct (hybrid) baryons in the flux–tube model of Isgur and Paton. In the limit of adiabatic quark motion, we build proper eigenstates of orbital angular momentum and construct the flavour, spin and J P of hybrid baryons from the symmetries of the system. The lowest-mass hybrid baryon is estimated at about GeV.
