Description

We question the reliability of current estimates for the Δ+ mass. We explain why the standard value, determined from pion photoproduction, should not be used in conjunction with present estimates for the Δ++ and Δ0 masses, determined from pion-nucleon scattering. The resultant mass splittings are internally inconsistent. We also briefly comment on discrepancies found when 'theoretical' and 'experimental' values for the Δ masses are compared. copyright 1997 The American Physical Society
