Remarks on the Delta(+) mass
arXiv:nucl-th/9705021 · doi:10.1103/PhysRevC.56.1645
Abstract
We question the reliability of current estimates for the Delta(+) mass. We explain why the standard value, determined from pion photoproduction, should not be used in conjunction with present estimates for the Delta(++) and Delta(0) 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 Delta masses are compared.
