Baryon Isovector Electric Properties and the Large Nc and Chiral Limits
Thomas D. Cohen
Abstract
A model independent calculation is given for the nucleon isovector electric charge radius which is valid in the limit Nc → ∞, mπ→ 0, Nc mπ fixed. This expression reduces to that of the Skyrme model in the limit Nc mπ → ∞.
