Abstract
String theory has no parameter except the string scale MS, so the Planck scale MPl, the supersymmetry-breaking scale m✘susy✘, the electroweak scale mEW as well as the vacuum energy density (cosmological constant) Λ are to be determined dynamically at any local minimum solution in the string theory landscape. Here we consider a model that links the supersymmetric electroweak phenomenology (bottom up) to the string theory motivated flux compactification approach (top down). In this model, supersymmetry is broken by a combination of the racetrack Kähler uplift mechanism, which naturally allows an exponentially small positive Λ in a local minimum, and the anti-D3-brane in the KKLT scenario. In the absence of the Higgs doublets in the supersymmetric standard model, one has either a small Λ or a big enough m✘susy✘, but not both. The introduction of the Higgs fields (with their soft terms) allows a small Λ and a big enough m✘susy✘ simultaneously. Since an exponentially small Λ is statistically preferred (as the properly normalized probability distribution P(Λ) diverges at Λ = 0+), identifying the observed Λobs to the median value Λ50% yields mEW ∼ 100 GeV. We also find that the warped anti-D3-brane tension has a SUSY-breaking scale M✘susy✘ ∼ 100 mEW while the SUSY-breaking scale that directly correlates with the Higgs fields in the visible sector m✘susy✘ ≈ mEW. © The Authors.
