The Cosmological Constant
by Sean M. Carroll
Publisher: arXiv 2000
Number of pages: 50
This is a review of the physics and cosmology of the cosmological constant. Focusing on recent developments, the author presents a pedagogical overview of cosmology in the presence of a cosmological constant, observational constraints on its magnitude, and the physics of a small (and potentially nonzero) vacuum energy.

A special solution of the Maxwell equations is presented, which disposes of the properties the Higgs-field must have, if it should not violate already secured perceptions and observations. If both fields are identical remains to be seen at this time.

Basics of inflationary models for the early universe, concentrating on the generation of density fluctuations from scalar-field dynamics. The subsequent gravitational dynamics of these fluctuations in dark matter in a Friedmann model are described.

We begin with a recapitulation of General Relativity, and the Standard Model of Cosmology. This is followed by lectures on inflation, density perturbations, study of hot and cold relics decoupled from the remaining constituents, and baryon asymmetry.

Cosmology and particle physics are deeply interrelated. Among the common problems are dark energy, dark matter and baryon asymmetry of the Universe. We discuss these problems in general terms, and concentrate on several particular hypotheses.
