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 de-scribe these systems with an RMS error smaller than 10％.We also perform a configurational entropy calculation in both models to discuss hadronic stability.
