On the consistency of the Aoki-phase
Stephen R. Sharpe
Lattice QCD with two flavors of Wilson fermions can exhibit spontaneous breaking of flavor and parity, with the resulting "Aoki phase" characterized by the non-zero expectation val…
Pion spectrum using improved staggered fermions
Taegil Bae, Jongjeong Kim, Weonjong Lee +1
We present results for the pion multiplet spectrum calculated using both unimproved staggered fermions and improved HYP-smeared staggered fermions. In the case of unimproved stagge…
in unquenched QCD using improved staggered fermions
Jongjeong Kim, Taegil Bae, Weonjong Lee +1
We present preliminary results for calculated using improved staggered fermions with a mixed action (HYP-smeared staggered valence quarks and AsqTad staggered sea quarks). We…
Discretization errors in the spectrum of the Hermitian Wilson-Dirac operator
Stephen R. Sharpe
I study the leading effects of discretization errors on the low energy part of the spectrum of the Hermitian Wilson-Dirac operator in infinite volume. The method generalizes that u…
Progress report on the staggered epsilon'/epsilon project
T. Bhattacharya, G. T. Fleming, G. Kilcup +3
We report on progress and future plans for calculating kaon weak matrix elements for epsilon'/epsilon using staggered fermions.
