The Higgs mass as a function of the compactification scale Original Research Article

We calculate to a few percent precision the Higgs potential in a model with supersymmetry broken by boundary conditions on an extra-dimension, compactified to a segment of length L, and a top quark quasi-localized on one of the two boundaries. 1/L alone, in the range 2–4 TeV, determines the Higgs mass, in the range 110–125 GeV, and the spectrum of gauginos, higgsinos and of the third-generation squarks. Lower values of 1/L cannot be excluded, with a progressive delocalization of the top quark.
