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…

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…

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…

Evidence for quenched chiral logs

W. Bardeen, A. Duncan, E. Eichten +1

Using the pole shifting procedure of the modified quenched approximation (MQA) to cure the exceptional configuration problem, accurate hadron hadron spectrum calculations can be ob…

Quenched Chiral Artifacts for Wilson-Dirac Fermions

W. Bardeen, A. Duncan, E. Eichten +1

We examine artifacts associated with the chiral symmetry breaking induced through the use of Wilson-Dirac fermions in lattice Monte Carlo computations. For light quark masses, the…
