DESCRIPTION:In this talk I will follow the work presented in a
rXiv:1912.10022 in which we consider local (or per
turbative) gauge anomalies in models featuring an
extra Z′ boson compared to the Standard Model (SM)
\, along with n SM-singlet fermions. Assuming that
the gauge group is compact\, we give a general so
lution to the anomaly cancellation conditions (ACC
s) for the ACCs that involve only SM fermions and
we examine whether a corresponding solution exists
for the remaining ACCs. We argue that this should
be adequate for the purposes of phenomenology\, a
t least for the time being. We show that a solutio
n to the remaining ACCs always exists for n≥5 in t
he family non-universal case or n≥3 in the family-
universal case. In the special case where only a s
ingle family carries non-vanishing charges\, we fi
nd a general solution to all ACCs\, for any value
of n.
