Natural supersymmetry from extra dimensions

© 2016 American Physical Society. We show that natural supersymmetry can be embedded in a five-dimensional theory with supersymmetry breaking à la Scherk-Schwarz (SS). There is no "gluino-sucks" problem for stops localized in the four-dimensional brane and gluinos propagating in the full five-dimensional bulk, and sub-TeV stops are easily accommodated. The μ/Bμ problem is absent as well; the SS breaking generates a Higgsino Dirac mass, and no bilinear Higgs mass parameter in the superpotential is required. Moreover, for nonmaximal SS twists leading to tanβ≃1, the Higgs spectrum is naturally split, in agreement with LHC data. The 125 GeV Higgs mass and radiative electroweak symmetry breaking can be accommodated by minimally extending the Higgs sector with Y=0 SU(2)L triplets.
