New Application of the large-Nc expansion : comparison of the Gottfried and Adler sum rules
D. J. Broadhurst, A. L. Kataev, C. J. Maxwell
The Adler sum rule for deep inelastic neutrino scattering measures the isospin of the nucleus, and is hence exact. In contrast the Gottfried sum rule for charged lepton scattering…
