Lattice QCD Calculations of Hadron Structure: Constituent Quarks and Chiral Symmetry
D. B. Leinweber, A. W. Thomas
Abstract
New data from parity-violating experiments on the deuteron now allow isolation of the strange-quark contribution to the nucleon magnetic moment, GMs(0), without the uncertainty surrounding the anapole moment of the nucleon. Still, best estimates place GMs(0) > 0. It is illustrated how this experimental result challenges the very cornerstone of the constituent quark model. The chiral physics giving rise to GMs(0) 0 is illustrated.
