Title: Chiral Abelian gauge theories with few fermions

Abstract

We construct chiral theories with the smallest number $$n_\chi$$ of Weyl fermions that form an anomaly-free set under various Abelian gauge groups. For the $U(1)$ group, where $$n_\chi = 5$$, we show that the general solution to the anomaly equations is a set of charges given by cubic polynomials in three integer parameters. For the $$U(1) \times U(1)$$ gauge group we find $$n_\chi = 6$$, and derive the general solution to the anomaly equations, in terms of 6 parameters. For $$U(1) \times U(1) \times U(1)$$ we show that $$n_\chi = 8$$, and present some families of solutions. These chiral gauge theories have potential applications to dark matter models, right-handed neutrino interactions, and other extensions of the Standard Model. As an example, we present a simple dark sector with a natural mass hierarchy between three dark matter components.
