# A new U(1) model anomaly free for three families to address fermion mass hierarchy and neutrino physics

@article{Mantilla2017ANU, title={A new U(1) model anomaly free for three families to address fermion mass hierarchy and neutrino physics}, author={Sebastian Mantilla and Roberto Mart{\'i}nez}, journal={arXiv: High Energy Physics - Phenomenology}, year={2017} }

A new non-universal abelian extension $\mathrm{G_{SM}}\otimes \mathrm{U(1)}_{X}$ to the Standard Model free from chiral anomalies is presented. The new $X$ charges distinguish among generations so as the fermion mass matrices get zero-textures from the fermion mass hierarchy can be obtained. Regarding to neutrino physics, the model inclues Majorana fermions which induce see-saw mechanisms to get small neutrino masses. Moreover, the suitability of the model is tested by searching for regions in…

In the framework of an nonuniversal $U(1)'$ extension of the standard model, we propose an scalar candidate for cold dark matter which exhibits interactions with ordinary matter through Higgs and…
