The Cosmological Constant and the Electroweak Scale

Abstract

String theory has no parameter except the string scale, so a dynamically compactified solution to 4 dimensional spacetime should determine both the Planck scale and the cosmological constant Λ\Lambda. In the racetrack K\"ahler uplift flux compactification model in Type IIB theory, where the string theory landscape is generated by scanning over discrete values of all the flux parameters, a statistical preference for an exponentially small Λ\Lambda is found to be natural (arXiv:1305.0753). Within this framework and matching the median Λ\Lambda value to the observed Λ\Lambda, a mass scale m100{\bf m}\simeq 100 GeV naturally appears. We explain how the electroweak scale can be identified with this mass scale.
