Anomaly Cancellation with an Extra Gauge Boson
B. C. Allanach, Ben Gripaios, Joseph Tooby‐Smith
Abstract
Many extensions of the standard model include an extra gauge boson, whose couplings to fermions are constrained by the requirement that anomalies cancel. We find a general solution to the resulting diophantine equations in the plausible case where the chiral fermion content is that of the standard model plus three right-handed neutrinos.
