摘要

Introduction:Since our last edition,there have been a few measurements of properties of the lowest A and ∑ resonances—mostly of masses and widths.But the field remains at a standstill.What follows is a much abbreviated version of the note on A and ∑ Resonances from our 1990 edition [1].In particular,see that edition for some representative Argand plots from partial-wave analyses.
