Effective Monopoles within Thick Branes

TL;DR

This paper investigates how monopole properties are altered in thick brane models, revealing modifications in mass and size, and discusses the implications of these changes along with quantum corrections and gauge field localization.

Contribution

It introduces a detailed analysis of monopole behavior in thick branes, including mass, radius, quantum corrections, and gauge field localization, highlighting new effects and constraints.

Findings

Monopole mass depends on position within the brane.

Monopole radius increases with brane thickness, leading to physical constraints.

Quantum corrections remain manageable despite modifications.

Abstract

The monopole mass is revealed to be considerably modified in the thick braneworld paradigm, and depends on the position of the monopole in the brane as well. Accordingly, the monopole radius continuously increases, leading to an unacceptable setting that can be circumvented when the brane thickness has an upper limit. Despite such peculiar behavior, the quantum corrections accrued -- involving the classical monopole solution -- are shown to be still under control. We analyze the monopole's peculiarities also taking into account the localization of the gauge fields. Furthermore, some additional analysis in the thick braneworld context and the similar behavior evinced by the topological string are investigated.
