THE RISE OF THE WIMP PARADIGM • We have learned a lot about the Universe in recent years • There is now overwhelming evidence that normal (atomic) matter is not all the matter in the Universe: Dark Matter: 23% ± 4% Dark Energy: 73% ± 4% Normal Matter: 4% ± 0.4% Neutrinos: 0.2% (Σmν/0.1eV) • To date, all evidence is from dark matter’s gravitational effects 23 Mar 11 Feng 4
DARK MATTER Known DM properties • Gravitationally interacting • Not short-lived • Not hot • Not baryonic Unambiguous evidence for new particles 23 Mar 11 Feng 5
