GeV dark matter in the Standard Model and beyond

10.06.2025 11:30 – 12:30

Astrophysical and cosmological observations unquestionably establish the existence of dark matter and its presence around us. Trying to uncover the properties of this substance requires us to ask how it could fit within the Standard Model or as an extension to it. In this talk, I will introduce GeV-scale dark matter, explain how its potential interaction with regular matter could lead to its capture and accumulation around dense bodies, and consider how this leads to bounds on its direct observation. I will first cover a specific candidate called the sexaquark, a potentially stable uuddss bound state. Then, I will evaluate the use of planetary probes, such as ultraviolet airglow and internal heat, to constrain candidates beyond the Standard Model with a broader mass range.
