Unlocking the Secrets of Exotic Pentaquarks

The study of pentaquark decay pathways-specifically [latex]Pc(4410) \rightarrow \eta_c \Delta[/latex] and [latex]Pc(4410) \rightarrow J/\psi \Delta[/latex]-reveals sensitivity to Borel window variations, suggesting a nuanced relationship between decay constants and the parameters used in analyzing hadron interactions.

A new systematic study using QCD sum rules sheds light on the decay patterns of recently discovered pentaquark states, helping to determine if they are tightly bound or loosely connected molecular structures.
