论文摘要
如当前和计划的实验中所探测的那样，可以通过涉及一个真实的，正，光谱密度函数的一般分散关系来捕获，这是由隐藏扇区标量运算符交换产生的第五力。先前认为的标量第五力，从树级到更外来的环路级别的可能性，是在这种形式主义中得出的，而无需明确执行常规环路计算。同一形式主义也呈现了第五力搜索中常用的各种实验性可观察物，从而可以直接提取任何特定模型上的限制。还讨论了探测隐藏部门违反单位性，因果关系或位置的推测可能性，这表现为光谱密度阳性的分解。
Fifth forces arising from hidden sector scalar operator exchange, as probed in a variety of present and planned experiments, can be captured by a general dispersion relation involving one real, positive, spectral density function. Previously considered scalar fifth forces, from tree-level to more exotic loop-level possibilities, are derived in this formalism, without explicitly performing conventional loop calculations. A variety of experimental observables commonly used in fifth force searches are also presented in the same formalism, allowing the straightforward extraction of limits on any specific model. The speculative possibility of probing hidden sector violations of unitarity, causality, or locality, manifested as a breakdown of the positivity of the spectral density, is also discussed.
