concordance (CMB, large-scale structure, BBN, …)<br />
CDM: 4% a<strong>to</strong>ms, 22% dark <strong>matter</strong>, 74% dark energy<br />
Cannot be explained with standard-model particles<br />
Popular hypothesis: WIMPs, e.g., supersymmetry →<br />
neutralinos with m ~ 100 GeV … TeV<br />
<br />
<br />

<br />
