Should the Strange Magnetic Moment of the Nucleon be Positive?

Abstract

The strange magnetic moment of the nucleon ($μ_s$) is examined as part of the nucleon's isoscalar anomalous moment. The dominant up and down quark effects in the anomalous moment may actually tend to favor $μ_s >0$, which is contrary to the negative values that generally result from model calculations. The possible origins of this apparent discrepancy are considered.
