Particle Physics Foundations of Dark Matter, Dark Energy, and Inflation (1/3) © CERN
Kolb, Edward (Rocky) (speaker) (University of Chicago)
CERN. Geneva
Academic Training Lecture Regular Programme
Ninety-five
percent of the present mass-energy density of the Universe is dark.
Twenty-five percent is in the form of dark matter holding together
galaxies and other large scale structures, and 70% is in the form of
dark energy driving an accelerated expansion of the universe. Dark
matter and dark energy cannot be explained within the standard model of
particle physics. In the first lecture I will review the evidence for
dark 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 hypothetical Weakly-Interacting Massive Particle, or WIMP, and
review experimental and observational approaches to test the hypothesis.
Finally, I will discuss how the LHC might shed light on the problem. In
the second lecture I will review the theoretical foundations and
observational evidence that the dominant component of the present mass
density of the Universe has a negative pressure, which leads to an
accelerated expansion of the Universe. I will then describe various
approaches to understand the phenomenon. Finally, I will describe an
observational program to understand the nature of dark energy. The third
lecture will describe the issues and models 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 will describe how present
observations can shed light on events that occurred in the first second
of the life of the universe.
