Supersymmetry Breaking and the Cosmological Constant

Abstract

I review three attempts to explain the small value of the cosmological constant, and their connection to SUSY breaking. They are The String Landscape, Supersymmetric Large Extra Dimensions (SLED), and the Holographic Space-time Formalism invented by Fischler and myself.

50 pages LaTeX2e, to be published in Int. J. Mod. Phys. A. The section on Supersymmetric Large Extra Dimensions is derived from C. Burgess' marvelous Les Houches lectures on this topic, arXiv:1309.4133 . This version corrects many typos and missing references from the previous one. Third version has corrections to references
