 | DeTar, Carleton | Equation of state for two flavor QCD at Nt=6 | We calculate the two flavor equation of state for QCD on lattices with lattice spacing a=(6T)21 and find that cutoff effects are substantially reduced compared to an earlier study using a=(4T)21. However, it is likely that significant cutoff effects remain. We fit the lattice data to expected forms ... | Phase transitions; Quark-gluon plasma; Chiral symmetry | 1997-06 |

 | 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 | Improving flavor symmetry in the Kogut-Susskind hadron spectrum | We study the effect of modifying the coupling of Kogut-Susskind quarks to the gauge field by replacing the link matrix in the quark action by a ‘‘fat link,'' or sum of link plus three-link paths. Flavor symmetry breaking, determined by the mass difference between the Goldstone and non-Goldston... | Kogut-Susskind quarks; Flavor symmetry; Fat links | 1997-02 |

 | Gondolo, Paolo | Indirect neutralino detection rates in neutrino telescopes | Neutralinos annihilating in the center of the Sun or the Earth may give rise to a detectable signal of neutrinos. We derive the indirect detection rates for neutrino telescopes in the minimal supersymmetric extension of the standard model. We show that even after imposing all phenomenological and e... | Neutralinos; Neutrino telescopes; Relic density; Annihilations | 1997-02 |

 | Gondolo, Paolo | Neutralino relic density including coannihilations | We evaluate the relic density of the lightest neutralino, the lightest supersymmetric particle, in the minimal supersymmetric extension of the standard model. For the first time, we include all coannihilation processes between neutralinos and charginos for any neutralino mass and composition. We u... | Neutralinos; Charginos; Higgsinos; Relic density; Coannihilations; Boltzmann equation | 1997-08 |

 | DeTar, Carleton | QCD thermodynamics with an improved lattice action | We have investigated QCD with two flavors of degenerate fermions using the Symanzik-improvement program for both the gauge and fermion actions. Our study focuses on the deconfinement transition on an Nt=4 lattice. Having located the thermal transition, we performed zero temperature simulations nea... | Wilson fermions; Polyakov loop; Chiral symmetry; Phase transitions | 1997-11 |
