Still, best estimates place G_M^s(0) > 0. It is illustrated how this experimental result challenges the very cornerstone of the constituent quark model. The chiral physics giving rise to G_M^s(0) \sim 0 is illustrated.enJournal article002001046710.1016/S0375-9474(01)00485-70001676287000052-s2.0-8501081837962005Leinweber, D.
