Abstract

We have calculated a variety of mesonic and baryonic correlation function using an instant on model of the QCD vacuum. These correlation functions can be used to determine the spectrum of physical states in each channel. The short distance behavior of the correlators is interesting in comparison with predictions from QCD sum rules based on the Operator Product Expansion. We find that the model not only predicts the masses and coupling constants of the lowest resonance in most channels but also reproduces the first lattice measurements of QCD point to point correlation functions.

Lattice analysis of two-point hadronic correlators in the QCD vacuum

Conference Chu, M; Grandy, J; Huang, S; ...

Results from the first lattice QCD analysis of vacuum correlators of local hadronic currents using dispersion relations are presented. We have explored the vector, pseudoscalar, axial, and scalar meson channels, and the proton-like and delta-like baryon channels. The lattice results are shown to agree qualitatively with experimental results in channels where experimental data exist, and shed insight into interacting instanton approximations and sum rule calculations in the other channels.

Correlation functions of hadron currents in the QCD vacuum calculated in lattice QCD

Journal Article Chu, M; Grandy, J; Huang, S; ... - Physical Review, D (Particles Fields); (United States)

Point-to-point vacuum correlation functions for spatially separated hadron currents are calculated in quenched lattice QCD on a 16[sup 3][times]24 lattice with 6/[ital g][sup 2]=5.7. The lattice data are analyzed in terms of dispersion relations, which enable us to extract physical information from small distances where asymptotic freedom is apparent to large distances where the hadronic resonances dominate. In the pseudoscalar, vector, and axial vector channels where experimental data or phenomenological information are available, semiquantitative agreement is obtained. In the nucleon and [Delta] channels, where no experimental data exist, our lattice data complement experiments. Comparison with approximations based on sum rulesmore »« less

Lattice calculation of point-to-point Hadron current correlation functions in the QCD vacuum

Journal Article Chu, M; Grandy, J; Huang, S; ... - Physical Review Letters; (United States)

Point-to-point correlation functions of hadron currents in the QCD vacuum are calculated on a lattice and analyzed using dispersion relations, providing physical information down to small spatial separations. Qualitative agreement with phenomenological results is obtained in channels for which experimental data are available, and these correlation functions are shown to be useful in exploring approximations based on sum rules and interacting instantons.

Hadron Spectroscopy and decay matrix elements in quenched lattice QCD

Miscellaneous Loft, R

The lowest lying hadronic masses were calculated in the quenched approximation of lattice QCD, using Wilson fermions on a 11{sup 3} {times} 20 lattice. The data set consisted of 20 pure SU(3) gauge configurations generated by Monte Carlo simulation, which are used as background fields for computing the quark propagators. The states considered included all possible combinations of the up, strange and charmed quarks. The lightest state masses were found to be: {rho} 645(100)MeV, nucleon 1091 (158) MeV, and {Delta}{sup ++} 1196 (190) MeV. The suppression of the vector-pseudoscalar meson splittings in our study could be explained by an overallmore »« less
