摘要

研究了洛伦兹不变性破坏（LIV）背景对（2,1）维全局结构能量正则化的影响。为此，我们考虑了一个复杂标量和固定三向量耦合作为高阶导数项的模型。我们证明了liv背景对中性整体结构的能量和运动方程没有影响。然而，我们观察到带电结构在电场中表现出对liv背景敏感的特征，电场的强度由liv参数控制。此外，所开发的程序导致具有有限能量和正则电场的一阶解。

On global vortices in the higher derivative Lorentz-violating scenario

We study the influence of Lorentz invariance violation (LIV) background in energy regularization of global structures in

–dimensions. To this end, we consider a model in which the complex scalar and fixed three-vector couple as a high derivative order term. We show that LIV-background does not affect the energy and the equation of motion of neutral global structures. However, we observe that the charged structures are sensitive to LIV-background by presenting signatures in the electric field whose intensity is controlled by the LIV-parameter. Furthermore, the procedure developed leads to first-order solutions with finite energy and a regularized electric field.
