Phenomenology of minimal Z' models: from the LHC to the GUT scale

Abstract

We consider a class of minimal abelian extensions of the Standard Model with an extra neutral gauge boson $Z^{\prime }$ at the TeV scale. In these scenarios an extended scalar sector and heavy right-handed neutrinos are naturally envisaged. We present some of their striking signatures at the Large Hadron Collider, the most interesting arising from a $Z^{\prime }$ decaying to heavy neutrino pairs as well as a heavy scalar decaying to two Standard Model Higgses. Using renormalisation group methods, we characterise the high energy behaviours of these extensions and exploit the constraints imposed by the embedding into a wider GUT scenario.
