Unquenching the Quark Model and Screened Potentials
arXiv:hep-ph/0504097 · doi:10.1088/0954-3899/31/7/025
Abstract
The low-lying spectrum of the quark model is shown to be robust under the effects of `unquenching'. In contrast, the use of screened potentials is shown to be of limited use in models of hadrons. Applications to unquenching the lattice Wilson loop potential and to glueball mixing in the adiabatic hybrid spectrum are also presented.
