Gauge and Higgs Boson Masses from an Extra Dimension

Abstract

We present novel calculations of the mass hierarchy of the $SU(2)$ pure gauge theory on a space-time lattice with an orbifolded fifth dimension. This theory has three parameters; the gauge coupling $\beta$, the anisotropy $\gamma$, which is a measure of the ratio of the lattice spacing in the four dimensions to that in the fifth dimension, and the extent of the extra dimension $N_5$. Using a large basis of scalar and vector operators we explore in detail the spectrum along the $\gamma =1$ line, and for the first time we investigate the spectrum for $\gamma \ne 1$.
