摘要:
In this study, we discuss the description of neutral Σ baryons with and 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. © 2025 Chinese Physical Society and the Institute of High Energy Physics of the Chinese Academ...
