Local Chirality of Low-Lying Dirac Eigenmodes and the Instanton Liquid Model
I. Horvath, S. J. Dong, T. Draper +6
The reasons for using low-lying Dirac eigenmodes to probe the local structure of topological charge fluctuations in QCD are discussed, and it is pointed out that the qualitative do…
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…
On The Origin of the OZI Rule in QCD
Nathan Isgur, H. B. Thacker
The OZI rule is prominent in hadronic phenomena only because OZI violation is typically an order of magnitude smaller than expected from large N_c arguments. With its standard ^3P_…
