A Note on Regularization methods in Kaluza-Klein Theories

Abstract

We comment on the presence of power-like divergences in Kaluza-Klein theories with supersymmetry breaking a là Scherk-Schwarz. By introducing a SUSY preserving regulator, we show that, in the context of a recently model proposed by Barbieri, Hall and Nomura, the Higgs mass is finite and unambiguously defined. The same result applies to similar models.
