Flavourful Z′ portal for vector-like neutrino dark matter and RK* $$ {R}_{K^{\left(*\right)}} $$
Abstract We discuss a flavourful Z′ portal model with a coupling to fourth-family singlet Dirac neutrino dark matter. In the absence of mixing, the Z′ is fermiophobic, having no couplings to the three chiral families, but does couple to a fourth vector-like family. Due to mixing effects, the Z′ gets...
