Insight into Hadron Structure from Lattice QCD
A variety of evidence from lattice QCD is presented revealing the dominant role of instantons in the propagation of light quarks in the QCD vacuum and in light hadron structure. The instanton content of lattice gluon configurations is extracted, and observables calculated from the instantons alone are shown to agree well with those calculated using all gluons. The lowest 128 eigenfunctions of t...
متن کاملHadron Structure Functions from Lattice QCD – 1997
We review the status of lattice calculations of the deep-inelastic structure functions of the nucleon. In addition, we present some results on the pion and rho structure functions.
متن کاملHadron Spectrum from Lattice QCD
A brief review is given of the lattice QCD calculation of the hadron spectrum. The status of current attempts toward inclusion of dynamical up, down and strange quarks is summarized focusing on our own work. Recent work on the possible existence of pentaquark states are assessed. We touch upon the PACS-CS Project for building our next machine for lattice QCD, and conclude with a near-term physi...
متن کاملHadron spectroscopy from lattice QCD
I present recent developments in the lattice QCD calculations of the light hadron spectrum. Emphasis is placed on the limitation of the quenched approximation in reproducing the observed spectrum and indications that the discrepancy is reduced by introducing two flavors of light dynamical quarks.
متن کاملHadron deformation from Lattice QCD
Hadronic matrix elements of twoand threecurrent correlators encode detailed information on hadron structure such as quark spatial distributions, charge radii and quadrupole moments. In the non-relativistic limit they reduce to the square of the wave function and therefore the shape of the hadron can be extracted. The issue of a deformation in the nucleon and ∆ was first examined in the context ...
