Pseudo-Goldstones from Supersymmetric Wilson Lines on 5D Orbifolds

Thomas Flacke, Babiker Hassanain, John March-Russell

We consider a U(1) gauge theory on the five dimensional orbifold ${\mathcal{M}}_4\times S^1/Z_2$, where $A_5$ has even $Z_2$ parity. This leads to a light pseudoscalar degree of free…
