Title: GeV dark matter in the Standard Model and beyond

Abstract: Astrophysical and cosmological observations unquestionably establish the existence of dark matter and its presence around us. In this talk, I will introduce GeV-scale dark matter, whose interaction with regular matter could lead to signatures in today’s most sensitive particle detectors. I will discuss the possibility of its capture and accumulation within dense astrophysical bodies, showing how this effect leads to complementary bounds on its direct observation. I will exemplify these ideas with a specific candidate called the sexaquark, a potentially stable uuddss bound state, also assessing how it could participate in dark matter’s cosmological abundance. Then, I will evaluate the use of planetary spectroscopy probes, such as ultraviolet airglow and internal heat, to constrain candidates beyond the Standard Model with a broader mass range.
