Within [Formula: see text] modified Weyl gravity, we consider a model of a spin-[Formula: see text] electric charge consisting of interior and exterior regions. The interior region is determined by quantum gravitational effects whose approximate description is carried out using Weyl gravity nonminimally coupled to a massless Dirac spinor field. The interior region is embedded in exterior Minkowski spacetime, and the joining surface is a two-dimensional torus. It is shown that mass, electric charge, and spin of the object suggested may be the same as those for a real electron.

F(B2) 修正外尔引力中的自旋 1/2 电荷模型

在[公式：见文本]修正的外尔引力中，我们考虑了一个自旋模型——[公式：见文本]电荷由内部和外部区域组成。内部区域由量子引力效应确定，其近似描述是使用非最小耦合到无质量狄拉克旋量场的外尔引力进行的。内部区域嵌入外部 Minkowski 时空，连接面是一个二维环面。结果表明，所建议的物体的质量、电荷和自旋可能与真实电子的质量、电荷和自旋相同。
