Electromagnetic corrections to masses and widths in the baryon decuplet, and to ?� d cross section at the ? resonance

Abstract

Abstract. The electromagnetic mass splittings of the A and F members of the decuplet are estimated and the resulting decay widths are calculated, assuming SU(2)-invariance of the coupling constants for "unmixed" states. Three additional Coulomb corrections occur when deuterons are used as neutron targets. The combined effects on rc• total cross sections are given.

Pion-Nucleus Interactions

“…It could be due to dynamical effects such as the neutron-proton mass difference, pro mixing in the n-nucleon interaction, etc. Regardless, it was parameterized (36) in terms of A mass and width differences (of a Breit-Wigner fo rm) as quoted in Table 1. Only the combinations There exist many models fo r estimating baryon mass differences.…”
