The realization that supersymmetry (SUSY), if softly broken at the weak scale, can stabilize the Higgs sector led many authors to explore the role it may play in particle physics. It was widely anticipated that superpartners would reveal themselves once the TeV scale was probed in high energy collisions. Experiments at the LHC have not yet revealed any sign for direct production of superpartners, or for any other physics beyond the Standard Model. This has led to some authors to question whether weak scale SUSY has a role to play in stabilizing the Higgs sector, and to seek alternate mechanisms for stabilizing the weak scale. We reevaluate the early arguments that led to the expectations for light superpartners, and show that SUSY models with just the minimal particle content may well be consistent with LHC (and other) data and simultaneously serve to stabilize the Higgs sector, if model parameters generally regarded as independent turned out to be appropriately correlated. In our view, it would be premature to ignore this possibility, given that we do not understand the underlying mechanism of SUSY breaking. We advocate using the electroweak scale quantity, Δ_EW, to determine whether a given SUSY spectrum might arise from a theory with low fine-tuning, even when the parameters correlations mentioned above are present. We find that (modulo technical caveats) all such models contain light higgsinos and that this leads to the possibility of new strategies for searching for SUSY. We discuss phenomenological implications of these models for SUSY searches at the LHC and its luminosity and energy upgrades, as well as at future electron-positron colliders. We conclude that natural SUSY, defined as no worse than a part in 30 fine-tuning, will not escape detection at a pp collider operating at 27 TeV and an integrated luminosity of 15 ab⁻¹, or at an electron-positron collider with a centre-of-mass energy of 600 GeV.

超对称性（SUSY）如果在弱尺度上软破裂，可以稳定希格斯区，这一认识使许多作者探索了它可能在粒子物理学中发挥的作用。人们普遍预计，一旦在高能碰撞中探测到TeV标度，超级伙伴就会展示自己。大型强子对撞机的实验尚未显示出直接生产超级合作伙伴或标准模型以外的任何其他物理的迹象。这导致一些作者质疑弱规模SUSY是否在稳定希格斯部门中发挥作用，并寻求替代机制来稳定弱规模。我们重新评估了导致轻型超级合作伙伴期望的早期争论，结果表明，如果通常认为独立的模型参数具有适当的相关性，那么仅具有最小颗粒含量的SUSY模型就很可能与LHC（和其他）数据保持一致，并且可以稳定希格斯扇形。我们认为，鉴于我们不了解SUSY破坏的潜在机制，现在忽略这种可能性为时过早。我们主张使用电弱标度量Δ_EW，即使存在上述参数相关性，也可以确定给定的SUSY频谱是否可能源自微调低的理论。我们发现（模态技术警告）所有此类模型均包含轻型希格诺现象，这导致寻找SUSY新策略的可能性。我们讨论了这些模型在大型强子对撞机及其光度和能量提升以及未来的电子-正电子对撞机上进行SUSY搜索的现象学意义。我们得出的结论是，自然SUSY（定义为不超过30次微调的一部分）不会在工作于27 TeV的pp对撞机和15 ab ^-1的积分光度的逃脱检测下，或在具有25 ab ^-1的电子-正电子对撞机上逃脱检测600 GeV的质心能量。
