| Abstract: Over the past several years, non-WIMP dark matter candidates have attracted a surge of interest in the particle physics community. In this two-part talk, I will summarize the underlying physics motivation for (and observable consequences of) a dark matter that is able to form a bound state of fundamental constituents. I will examine the astrophysical implications of a dark fermion that can form two-body bound states and some ongoing theoretical work to elucidate the dark sector ingredients necessary to lead to "successful" late-time fusion phenomenology. |
