AI总结:

本文从功能重整化群视角研究质量维为一的费米子相互作用结构,探讨ELKO旋量作为暗物质候选者的性质及标量-ELKO系统在重整化群流中的表现。

摘要:

本文首次系统地研究了由ELKO旋量描述的质量维为一的费米子的重整化群性质。通过构造,ELKOs必须对任何标准模型电荷中性,因此提供了一种自然的暗物质候选者。我们考虑了两种标量-ELKO系统的版本:第一种由导数约尔达-型相互作用特征化,而第二种则包含ELKO四费米子相互作用以及标量-ELKO通道。我们还考虑了由ELKOs通过保罗-型项与阿贝尔规范场相互作用的系统。在所有情况下,我们确定了由一致的重整化群流要求的最小相互作用集,并讨论了基于渐近自由构造紫外完整轨迹的可能性。我们使用功能重整化群作为研究方法。

英文摘要:

In this paper, we provide the first systematic investigation of renormalization group properties of mass dimension one fermions described by ELKO spinors. By construction, ELKOs must be neutral under any Standard Model charge, therefore, providing a natural candidate for dark matter. We consider two versions of scalar-ELKO systems: the first characterized by a derivative Yukawa-like interaction, while the second involves ELKO four-fermion interactions as well as a scalar-ELKO portal. We also considered a system composed of ELKOs interacting with an Abelian gauge field via Pauli-like term. In all cases, we identified the minimal set of interactions that are required by a consistent renormalization group flow, and we discussed the possibility of constructing UV-complete trajectories based on asymptotic freedom. We used the functional renormalization group as a method of investigation.
