Twin Higgs (TH) models explain the absence of new colored particles responsible for natural electroweak symmetry breaking (EWSB). All known ultraviolet completions of TH models require some nonperturbative dynamics below the Planck scale. We propose a supersymmetric model in which the TH mechanism is introduced by a new asymptotically free gauge interaction. The model features natural EWSB for squarks and gluino heavier than 2 TeV even if supersymmetry breaking is mediated around the Planck scale, and has interesting flavor phenomenology including the top quark decay into the Higgs boson and the up quark which may be discovered at the LHC.
双希格斯（TH）模型解释了不存在负责自然电弱对称性破缺（EWSB）的新有色粒子。所有已知的 TH 模型的紫外完全性都需要普朗克尺度以下的某种非微扰动力学。我们提出了一个超对称模型，其中 TH 机制是通过一种新的渐近自由规范相互作用引入的。该模型具有自然的 EWSB，即使 SUSY 破缺是在普朗克尺度附近传递的，对于比 2 TeV 还重的 squarks 和 gluino 也是如此，并且具有有趣的味现象学，包括 top 夸克衰变为希格斯玻色子和上夸克，这些可能在 LHC 中被发现。
