Renormalized masses of heavy Kaluza-Klein states

TL;DR

This paper discusses methods for calculating radiative corrections to heavy boson masses in Kaluza-Klein theory, emphasizing that a higher-dimensional approach best captures the essential physical properties.

Contribution

It introduces an intrinsically higher-dimensional method for computing radiative corrections in Kaluza-Klein models, highlighting its advantages over other approaches.

Findings

Higher-dimensional approach captures all physical properties.

Different methods of computing radiative corrections are compared.

Higher-dimensional approach is argued to be the most consistent.

Abstract

Several ways of computing the radiative corrections to the heavy boson masses in Kaluza-Klein theory are discussed. It is argued that only an intrinsically higher dimensional approach embodies all the desired physical properties.
