The Higgs mass and natural supersymmetric spectrum from the landscape

In supersymmetric models where the superpotential μ   term is generated with μ≪msoftμ≪msoft (e.g.   from radiative Peccei–Quinn symmetry breaking or compactified string models with sequestration and stabilized moduli), and where the string landscape 1. favors soft supersymmetry (SUSY) breaking terms as large as possible and 2. where the anthropic condition that electroweak symmetry is properly broken with a weak scale mW,Z,h∼100 GeVmW,Z,h∼100 GeV (i.e. not too weak of weak interactions), then these combined landscape/anthropic requirements act as an attractor   pulling the soft SUSY breaking terms towards values required by models with radiatively-driven naturalness: near the line of criticality where electroweak symmetry is barely broken and the Higgs mass is ∼125 GeV∼125 GeV. The pull on the soft terms serves to ameliorate the SUSY flavor and CP problems. The resulting sparticle mass spectrum may barely be accessible at high-luminosity LHC while the required light higgsinos should be visible at a linear e+e−e+e− collider with s>2m(higgsino).
