 Searches for new physics involving massive invisible particles / Burr, Jonathan One of the most obvious problems with the Standard Model is the lack of any explanation for dark matter: a form of matter predicted from astrophysical observations but not compatible with any known subatomic particle [...] CERN-THESIS-2018-255 - 178 p.
