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…

Background Enhancement of CPT Reach at an Asymmetric Phi Factory

Nathan Isgur, Alan Kostelecky, Adam Szczepaniak

Photoproduction of neutral-kaon pairs is studied from the perspective of CP and CPT studies. Interference of the P and S waves, with the former due to diffractive phi production an…

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…

Quark-Hadron Duality in Structure Functions

N. Isgur, S. Jeschonnek, W. Melnitchouk +1

While quark-hadron duality is well-established experimentally, the current theoretical understanding of this important phenomenon is quite limited. To expose the essential features…

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…
