# Towards a $Z'$ Gauge Boson in Noncommutative Geometry

@article{Krajewski1996TowardsA, title={Towards a \$Z'\$ Gauge Boson in Noncommutative Geometry}, author={Thomas Krajewski and I. E. Pris}, journal={arXiv: High Energy Physics - Theory}, year={1996} }

We study all possible $U(1)$-extensions of the standard model (SM) in the framework of noncommutative geometry (NCG) with the algebra $\hhh\op\cc\op\cc\op M_3(\cc)$. Comparison to experimental data about the mass of a hypothetical $Z'$ gauge boson leads to the necessity of introducing at least one new family of heavy fermions.

It is pointed out that charge quantization is implied without reference to grand unification, and in the absence of any reference to Higgs particles, anomaly cancellation among the standard-model fermions yields two possible hypercharge assignments. Expand
