Description
The $U(1)$ extensions of the standard model have the potential to explain several
beyond the standard model phenomena at the cost of predicting the existence of $Z'$, a new
neutral gauge boson. In the simplest scenario $Z'$ acquires its mass
from the spontaneous breaking of a new scalar field, also predicting a new scalar boson $s$. We show that taking into account the combined effects of $s$ and $Z'$ yields a severe exclusion limit on the free parameters of the model.
