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…
Hadronic Correlators from All-point Quark Propagators
A. Duncan, E. Eichten, J. Yoo
A method for computing all-point quark propagators is applied to a variety of processes of physical interest in lattice QCD. The method allows, for example, efficient calculation o…
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…
String Breaking in Four Dimensional Lattice QCD
A. Duncan, E. Eichten, H. Thacker
Virtual quark pair screening leads to breaking of the string between fundamental representation quarks in QCD. For unquenched four dimensional lattice QCD, this (so far elusive) ph…
Anomalous Chiral Behavior in Quenched Lattice QCD
W. Bardeen, A. Duncan, E. Eichten +1
A study of the chiral behavior of pseudoscalar masses and decay constants is carried out in quenched lattice QCD with Wilson fermions. Using the modified quenched approximation (MQ…
Chiral Effects of Quenched Eta-Prime Loops
W. Bardeen, A. Duncan, E. Eichten +1
Preliminary results of a study of quenched chiral logarithms at beta=5.7 are presented. Four independent determinations of the quenched chiral log parameter delta are obtained. Two…
