摘　　要：In this study,we discuss the description of neutral Σ baryons with I(J^(P))=1(1/2^(+))and I(J^(P))=1(3/2^(+))using two bottom-up approaches:the deformed background and static dilaton models.In both models,we consider a non-linear Regge trajectory extension motivated by the strange nature of Σ baryons.We find that both models describe these systems with an RMS error smaller than 10%.We also perform a configurational entropy calculation in both models to discuss hadronic stability.
