 | DeTar, Carleton | Exotic mesons in quenched lattice QCD | Since gluons in QCD are interacting fundamental constituents just as quarks are, we expect that in addition to mesons made from a quark and an antiquark, there should also be glueballs and hybrids ~bound states of quarks, antiquarks, and gluons!. In general, these states would mix strongly with th... | Hybrid mesons; Antiquarks | 1997-12 |

 | DeTar, Carleton | Hadronic deformation energy. I. Quark-antiquark separation | The MIT bag model for hadrons is treated in the static cavity approximation in three dimensions with a definite quark number. The energy of the system is computed to second order in the gluon coupling. A constrained variational method is described which permits the calculation of the energy as a f... | Bag models; Quark bag; Deformation energy; Antiquarks; Gluon coupling; Quark energies; Gluon energies | 1978-01 |

 | DeTar, Carleton | Static quark potential in three flavor QCD | We study the effects of dynamical quarks on the static quark potential at distances shorter than those where string breaking is expected. Quenched calculations and calculations with three flavors of dynamical quarks are done on sets of lattices with the lattice spacings matched within about one pe... | Dynamical quarks; Antiquarks; Static potential | 2000-07 |

 | DeTar, Carleton | String breaking in lattice quantum chromodynamics | The separation of a heavy quark and antiquark pair leads to the formation of a tube of flux, or string, which should break in the presence of light quark-antiquark pairs. This expected zero temperature phenomenon has proven elusive in simulations of lattice QCD. We present simulation results that sh... | String breaking; Antiquarks; Polyakov loop; Dynamical fermions | 1998-12 |
