Quest for eternal oscillons

Nonlinear field theories produce unstable but long-lived configurations known as oscillons. These structures have been studied with asymmetric and symmetric double-well potentials and extended to other forms of potentials. In the present work, we examine the consequences of considering higher-order field theories, where we have used a generalization of the symmetric double-well potential and a 06 potential. Consequently, we have found 3 + 1 spherically symmetric oscillons with significantly large lifetimes without parameter fine-tuning.
