Unquenched Studies Using the Truncated Determinant Algorithm
A. Duncan, E. Eichten, H. Thacker
A truncated determinant algorithm is used to study the physical effects of the quark eigenmodes associated with eigenvalues below 420 MeV. This initial high statistics study focuse…
Chiral Loop Effects in the Quenched Scalar Isovector Propagator
W. Bardeen, A. Duncan, E. Eichten +1
The scalar isovector meson propagator is studied in quenched QCD. For the lightest quark masses used, this propagator is dominated by a quenched chiral loop effect associated with…
Topological Charge Fluctuations and Low-Lying Dirac Eigenmodes
S. J. Dong, T. Draper, I. Horvath +5
We discuss the utility of low-lying Dirac eigenmodes for studying the nature of topological charge fluctuations in QCD. The implications of previous results using the local chirali…
Chiral Loops and Ghost States in the Quenched Scalar Propagator
W. Bardeen, A. Duncan, E. Eichten +2
The scalar, isovector meson propagator is analyzed in quenched QCD, using the MQA pole-shifting ansatz to study the chiral limit. In addition to the expected short-range exponentia…
Evidence Against Instanton Dominance of Topological Charge Fluctuations in QCD
Ivan Horvath, Nathan Isgur, John McCune +1
The low-lying eigenmodes of the Dirac operator associated with typical gauge field configurations in QCD encode, among other low-energy properties, the physics behind the solution…
