Not Strange but Bizarre Physics from the SAMPLE Experiment
Abstract
Since the report of the SAMPLE Collaboration suggesting the strange-quark contribution to nucleon magnetic moments, GMs(0), may be greater than zero, numerous models have appeared supporting positive values for GMs(0). In this paper the bizarre physics associated with GMs(0) > 0 is illustrated. Using new lattice QCD results, our best estimate for GMs(0) shifts slightly from GMs(0) = -0.75 +/- 0.30 muN, to GMs(0) = -0.62 +/- 0.26 muN.
