Fine Structure Constant in the Spacetime of a Cosmic String
arXiv:hep-th/0505150 · doi:10.1016/j.physletb.2005.04.012
Abstract
We calculate the fine structure constant in the spacetime of a cosmic string. In the presence of a cosmic string the value of the fine structure constant reduces. We also discuss on numerical results.
