We present a new class of models that stabilize the weak scale against radiative corrections up to scales of order 5 TeV without large corrections to precision electroweak observables. In these `folded supersymmetric' theories the one loop quadratic divergences of the Standard Model Higgs field are cancelled by opposite spin partners, but the gauge quantum numbers of these new particles are in general different from those of the conventional superpartners. This class of models is built around the correspondence that exists in the large N limit between the correlation functions of supersymmetric theories and those of their non-supersymmetric orbifold daughters. By identifying the mechanism which underlies the cancellation of one loop quadratic divergences in these theories, we are able to construct simple extensions of the Standard Model which are radiatively stable at one loop. Ultraviolet completions of these theories can be obtained by imposing suitable boundary conditions on an appropriate supersymmetric higher dimensional theory compactified down to four dimensions. We construct a specific model based on these ideas which stabilizes the weak scale up to about 20 TeV and where the states which cancel the top loop are scalars not charged under Standard Model color. Its collider signatures are distinct from conventional supersymmetric theories and include characteristic events with hard leptons and missing energy.

Searching for long-lived particles beyond the Standard Model at the Large Hadron Collider (2019, methodology): “The most striking signatures here are exotic Higgs decays to low-mass particles [117] (as in many Hidden Valley (HV) scenarios [66, 67]), which can arise in models of neutral naturalness [13, 14, 118] and DM [119], as well as in more exotic scenarios such as relaxion models [120].”
Higgs Physics at the HL-LHC and HE-LHC (2019, background): “The presence of long-lived particles (LLP) can be a striking feature of many new physics models [802, 803, 804, 805, 806, 807, 808, 809, 810, 811, 812, 813].”
The State of Supersymmetry after Run I of the LHC (2013, background): “There is an exceptionally intriguing class of models that have retrieved little attention in recent years but become increasingly appealing in light of LHC superpartner limits: “folded” supersymmetry [85], in which the top partners at low energies are neutral under QCD.”
A facility to search for hidden particles at the CERN SPS: the SHiP physics case (2015, background): “Hidden Valleys also arise in the context of “dark” solutions to naturalness, also known as “neutral naturalness” models, such as the Twin Higgs [188] and folded supersymmetry [189], where the top partner does not carry Standard Model color.”
Discovering uncolored naturalness in exotic Higgs decays (2015, background): “The first and prototypical examples of such theories are the Twin Higgs [29] and Folded SUSY [30] models.”
Physics at a 100 TeV pp collider: Higgs and EW symmetry breaking studies (2016, methodology): “An especially enticing scenario for the 100 TeV collider are theories of Neutral Naturalness, like the Twin Higgs [280] or Folded SUSY [281].”
Illuminating dark photons with high-energy colliders (2014, background): “Hidden sectors near the weak scale are motivated by naturalness [15–19], thermal dark matter [20–22], electroweak baryogenesis (see e.”
Physics opportunities of a 100 TeV proton–proton collider (2015, methodology): “Due to theoretical motivation in the context of both natural SUSY and split SUSY models, this final state is a very important signature of new physics to consider.”
A Quirky Little Higgs Model (2008, background): “How could quirks solve the little hierarchy problem? Recall that in the folded SUSY model [5], the quadratic divergence from the top quark is cancelled by its folded-partner, which is a spin-0 scalar not charged under the SM SU(3)C color gauge group.”
