Non-Abelian Vector Boson as FIMP Dark Matter

Abstract

In this analysis we demonstrate the freeze-in realization of a non-abelian vector boson dark matter (DM). We choose to elaborate an existing $SU(2{)}_N$ extension ($N$ stands for neutral) of the Standard Model (SM) with an additional $U(1)=S^{{}^{\prime }}$ global symmetry, which stabilizes the vector boson ($X,\bar{X}$) as DM through unbroken $S=T_{3N}+S^{{}^{\prime }}$ and as lightest odd $S$ particle. The analysis reveals that the contribution to the freeze-in production of DM from the decay of a heavier scalar bidoublet ${\zeta }_1^{0,\pm }\to {\zeta }_2^{0,\pm }X$ is important even after the freeze-out of ${\zeta }_1^{0,\pm }$ in equilibrium with thermal bath. Moreover, the neutral component of $SU(2{)}_N$ scalar triplet ($\Delta$), responsible for neutrino mass generation in this framework, turns out to serve as additional DMs in the model and offers a multipartite freeze-in DM set up to explore. The allowed parameter space is obtained after estimating constraints from CMB, BBN and AMS-02 bound. This exercise nicely complements the freeze-out realization of ($X,\bar{X}$) as weakly interacting massive particle (WIMP) and distinguishes it through stable charge track signature at collider compared to leptonic signal excess as found in WIMP scenario.
