论文摘要
非线性场理论产生了不稳定但长期寿命的构型，称为oscillons。这些结构已经用不对称和对称的双孔电势研究，并扩展到其他形式的电势。在目前的工作中，我们研究了考虑高阶现场理论的后果，在这种情况下，我们使用了对称双孔电位的概括和$ ϕ^6 $势。因此，我们发现了$ 3+1 $的球形对称oscillons，其生命值大得多，而没有参数进行微调。
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 $ϕ^6$ potential. Consequently, we have found $3+1$ spherically symmetric oscillons with significantly large lifetimes without parameter fine-tuning.
