P1: dark matter made of?
- not patrons, neutrons, black hole, massive stars
P2: not neutrinos - was possible but too lightweight
- hot
P3: the best fit for cold dark matter is undiscovered particle
extension of the standard model has examples
P4: suppersymmetry - a whole new family of particles - superpartner
- heavier
- candidate - neutralino (V)
neutralino is not neutrino
P5: neutralino - lightest supersymmetric particle - stable
- 0 charge
- satisfy all requirements of cold dark matter
