DESCRIPTION:Ninety-five percent of the present mass-energy density of the 
 Universe is dark.  Twenty-five percent is in the form of dark matter holdi
 ng together galaxies and other large scale structures\, and 70% is in the 
 form of dark energy driving an accelerated expansion of the universe.  Dar
 k matter and dark energy cannot be explained within the standard model of 
 particle physics.  In the first lecture I will review the evidence for dar
 k matter and the observations that point to an explanation in the form of 
 cold dark matter.  I will then describe the expected properties of a hypot
 hetical Weakly-Interacting Massive Particle\, or WIMP\, and review experim
 ental and observational approaches to test the hypothesis.  Finally\, I wi
 ll discuss how the LHC might shed light on the problem.  In the second lec
 ture I will review the theoretical foundations and observational evidence 
 that the dominant component of the present mass density of the Universe ha
 s a negative pressure\, which leads to an accelerated expansion of the Uni
 verse.  I will then describe various approaches to understand the phenomen
 on.  Finally\, I will describe an observational program to understand the 
 nature of dark energy. The third lecture will describe the issues and mode
 ls associated with primordial inflation\, the purported rapid expansion of
  the universe in the first fraction of a second after the bang.  Models of
  inflation also involve beyond the standard model physics.  The lecture wi
 ll describe how present observations can shed light on events that occurre
 d in the first second of the life of the universe.\n\nhttp://indico.cern.c
