摘要

隐藏扇区超对称破缺（其中带电的隐藏扇区场获得了SUSY破缺真空期望值）曾经在动态SUSY破缺（DSB）中很常见。在这种情况下，标量可以获得较大的质量，但高规子和a项获得环抑制的异常介导的贡献，这可能比1/16π2 ~ 1/160小。这种情况导致了诸如PeV或微裂超对称的模型，其尺度为~ 160maugino。为了产生轻希格斯质量mh≃125 GeV，在10-100 TeV范围内需要标量质量项，这导致了对弱尺度的巨大非自然贡献。或者，在单线态隐藏扇形场的重力中介中，即使自然值为mt ~ 1 ~ 1 - 3 TeV， mscalars ~ mgauginos ~ a项和大a项也能使mh→125 GeV。需要自然性，这似乎是弦景观的概率偏好，那么测量的希格斯质量似乎更倾向于隐藏区域的单线态，这在亚稳态和改进的DSB模型中很常见。2025年由美国物理学会出版

Implications of Higgs mass for hidden sector SUSY breaking

Hidden sector supersymmetry (SUSY) breaking where charged hidden sector fields obtain SUSY breaking vacuum expectation values once seemed common in dynamical SUSY breaking (DSB). In such a case, scalars can obtain large masses but gauginos and A-terms gain loop-suppressed anomaly-mediated contributions which may be smaller by factors of 1/16π2∼1/160. This situation leads to models such as PeV or minisplit supersymmetry with mscalars∼160mgaugino. In order to generate a light Higgs mass mh≃125 GeV, the scalar mass terms are required in the 10–100 TeV range, leading to large, unnatural contributions to the weak scale. Alternatively, in gravity mediation with singlet hidden sector fields, then mscalars∼mgauginos∼A-terms and the large A-terms lift mh→125 GeV even for natural values of mt˜1∼1–3 TeV. Requiring naturalness, which seems probabilistically preferred by the string landscape, then the measured Higgs mass seems to favor singlets in the hidden sector, which can be common in metastable and retrofitted DSB models.
