Description
U(1) extensions of the Standard Model have received significant attention.
However, concrete examples with anomalies in the effective low-energy
theory remain scarce.
We present a model with three main features. First, it includes a
hierarchy between fermions charged under the new U(1) and the new gauge
boson, leading to an apparent anomaly at low energies. Second, it provides
a viable Dark Matter candidate. Third, it improves gauge coupling
unification.
The construction includes a secluded fermion sector with N families of
vector-like Standard Model-like representations. We discuss the
limitations of a minimal implementation and introduce viable examples.
The parameter space is explored using machine learning algorithms. We
derive constraints from Dark Matter direct detection and collider
searches.
