Model of a spin-$1\mathrm{/}2$ electric charge in $F\left(B^2\right)$ modified Weyl gravity

Within $F\left(B^2\right)$ modified Weyl gravity, we consider a model of a spin-$1\mathrm{/}2$ 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.
