Corrections to the fine structure constant in higher dimensional global monopole spacetime

TL;DR

This paper investigates how the Generalized Uncertainty Principle modifies the fine structure constant in higher-dimensional global monopole spacetimes, providing specific results for various dimensions including the physically relevant 3+1 case.

Contribution

It introduces corrections to the fine structure constant in higher-dimensional global monopole spacetimes using the Generalized Uncertainty Principle, extending previous work to arbitrary dimensions.

Findings

Derived explicit correction formulas for the fine structure constant in (D+1)-dimensional spacetime.

Specialized the general results to the physically relevant 3+1-dimensional case.

Provided insights into the effects of higher dimensions on fundamental constants.

Abstract

In this paper we use the Generalized Uncertainty Principle in order to obtain the corrections to the fine structure constant in (D+1)-dimensional global monopole spacetime. The result is particularized to D-dimensional spacetime. We also discuss the particular case D=3 corresponding to the (3+1)-dimensional global monopole spacetime.
