Flavor symmetry breaking and scaling for improved staggered actions in quenched QCD
M. Cheng, N. H. Christ, C. Jung +4
We present a study of the flavor symmetry breaking in the pion spectrum for various improved staggered fermion actions. To study the effects of link fattening and tadpole improveme…
The Ground State of the Pseudogap in Cuprate Superconductors
T. Valla, A. V. Fedorov, Jinho Lee +2
We present studies of the electronic structure of La2-xBaxCuO4, a system where the superconductivity is strongly suppressed as static spin and charge orders or "stripes" develop ne…
First results from 2+1-Flavor Domain Wall QCD: Mass Spectrum, Topology Change and Chiral Symmetry with
D. J. Antonio, T. Blum, K. C. Bowler +23
We present results for the static interquark potential, light meson and baryon masses, and light pseudoscalar meson decay constants obtained from simulations of domain wall QCD wit…
Perturbative renormalization for static and domain-wall bilinears and four-fermion operators with improved gauge actions
Oleg Loktik, Taku Izubuchi
We calculate one-loop renormalization factors for heavy-light bilinears as well as four-fermion operators relevant for mixing calculations on the lattice. We…
Fuzzy Bags and Wilson Lines
Robert D. Pisarski
I start with an elementary observation about the pressure in the deconfined phase of a SU(3) gauge theory without quarks. This suggests a ``fuzzy'' bag model for the analogous pres…
Measurement of the ppbar to ttbar production cross section at sqrt(s)=1.96 TeV in the fully hadronic decay channel
D0 Collaboration, V. Abazov
A measurement of the top quark pair production cross section in proton anti-proton collisions at an interaction energy of sqrt(s)=1.96 TeV is presented. This analysis uses 405 pb-1…
