Multipole vector dark matter below the GeV scale

We consider electrically neutral complex vector particles $V$ below the GeV mass scale that, from a low energy perspective, couple to photon via higher dimensional form factor interactions. derive ensuing astrophysical constraints by considering anomalous loss Sun, Horizontal Branch, and Red Giant stars as well SN1987A that arise pair-production in these environments. Under assumption dark states constitute matter, bounds are then complemented direct indirect detection cosmological limits. The relic density freeze-out freeze-in mechanisms is also computed. On basis of UV-complete model realizes considered effective couplings, we discuss naturalness constrained parameter space, provide an analysis zero limit $V$.
