摘要

The accompanying table gives our evaluation of the present status of the Ξ resonances.Not much is known about Ξ resonances.This is because (1) they can only be produced as a part of a final state,and so the analysis is more complicated than if direct formation were possible,(2) the production cross sections are small (typically a few μb),and (3) the final states are topologically complicated and difficult to study with electronic techniques.Thus early information about Ξ resonances came entirely from bubble chamber experiments,where the numbers of events are small,and only in the 1980's did electronic experiments make any significant contributions.However,nothing of significance on Ξ resonances has been added since our 1988 edition.
