Abstract
New data from parity-violating experiments on the deuteron now allow isolat ion of the strange-quark contribution to the nucleon magnetic moment, G(M)( s)(0), without the uncertainty surrounding the anapole moment of the nucleo n. Still, best estimates place G(M)(s)(0) > 0. It is illustrated how this e xperimental result challenges the very cornerstone of the constituent quark model. The chiral physics giving rise to G(M)(s)(0) similar to 0 is illust rated.
