Abstract

Strong empirical and phenomenological indications exist for large sea-quark admixtures in the low-lying excited baryons.Investigating the low-lying excited baryon ∑*(1/2-)is important for determining the nature of the low-lying excited baryons.We review the experimental and theoretical progress on the studies of the ∑*(1/2-).Although several candidates have received intensive discussions,such as ∑(1620)and ∑(1480),their existence needs further confirmation.Following the prediction of the unquenched quark models for the ∑*(1/2-),many theoretical works suggested the existence of these states in various processes.Future experimental measurements could shed light on the existence of the low-lying excited ∑*(1/2-)state.
