Particle Dark Matter
  There is plenty of evidence that most matter in the Universe is dark (non-luminous). Particle physics offers several possible explanations. In this talk I focus on cold dark matter; the most promising candidates are then axions and the lightest supersymetric particle. I briefly summarize estimates of the present relic density of these particles, and describe efforts to detect them
