Self-interacting dark matter with a vector mediator: kinetic mixing with the U 1 B − L 3 $$ \mathrm{U}{(1)}_{{\left(B-L\right)}_3} $$ gauge boson

Self-interacting dark matter with a vector mediator: kinetic mixing with the U 1 B − L 3 $$ \mathrm{U}{(1)}_{{\left(B-L\right)}_3} $$ gauge boson

Abstract A spontaneously broken hidden U(1) h gauge symmetry can explain both the dark matter stability and the observed relic abundance. In this framework, the light gauge boson can mediate the strong dark matter self-interaction, which addresses astrophysical observations that are hard to explain...
