论文摘要
在超对称（SUSY）理论中，在IR字段内容和参数方面，Higgs质量的IR量贡献可以在中介量表$λ_{\ text {uv}} $下计算。但是，$λ_ {\ text {uv}} $对物理的敏感性仍然存在。在这项工作中，我们提供了一个由对称性决定的框架的第一个示例，以使这些对数超过物质部门。结果是对Higgs质量进行有限的，可估计的校正的模型。这需要引入新字段 - “伐木工人”的角色是筛选紫外线敏感的日志。这些模型的微调大大降低了，而不是高度超对称的数量级。这影响了对自然参数空间的解释，这表明宣布高规模SUSY的自然危机可能为时过早。
In a supersymmetric (SUSY) theory, the IR-contributions to the Higgs mass are calculable below the mediation scale $Λ_{\text{UV}}$ in terms of the IR field content and parameters. However, logarithmic sensitivity to physics at $Λ_{\text{UV}}$ remains. In this work we present a first example of a framework, dictated by symmetries, to supersoften these logarithms from the matter sector. The result is a model with finite, IR-calculable corrections to the Higgs mass. This requires the introduction of new fields -- the `lumberjacks' -- whose role is to screen the UV-sensitive logs. These models have considerably reduced fine-tuning, by more than an order of magnitude for high scale supersymmetry. This impacts interpretations of the natural parameter space, suggesting it may be premature to declare a naturalness crisis for high-scale SUSY.
