Non-universal Z′ from fluxed GUTs
We make a first systematic study of non-universal TeV scale neutral gauge bosons Z′ arising naturally from a class of F-theory inspired models broken via SU(5) by flux. The phenomenological models we consider may originate from semi-local F-theory GUTs arising from a single E8 point of local enhance...
