论文摘要
我们使用最近的电偶极矩（EDM）测量数据来限制HFF $^+$ EDM由于与候选暗物质类轴突样粒子（ALP）的相互作用而及时振荡的可能性。我们采用了一种贝叶斯分析方法，该方法既说明了位置的效果，又是与ALP场中随机密度波动相关的不确定性。我们没有发现从27 nhz到400 MHz的范围内振荡EDM的证据，我们使用此结果将ALP-Gluon耦合限制在质量范围上的$ 10^{ - 22} -10^{ - 15} $ ev。这是$ 10^{ - 17} -10^{ - 15} $ eV范围的ALP-Gluon耦合的第一个实验室限制，也是第一个实验室约束，以正确地说明ALP字段的随机性质。
We use our recent electric dipole moment (EDM) measurement data to constrain the possibility that the HfF$^+$ EDM oscillates in time due to interactions with candidate dark matter axion-like particles (ALPs). We employ a Bayesian analysis method which accounts for both the look-elsewhere effect and the uncertainties associated with stochastic density fluctuations in the ALP field. We find no evidence of an oscillating EDM over a range spanning from 27 nHz to 400 mHz, and we use this result to constrain the ALP-gluon coupling over the mass range $10^{-22}-10^{-15}$ eV. This is the first laboratory constraint on the ALP-gluon coupling in the $10^{-17}-10^{-15}$ eV range, and the first laboratory constraint to properly account for the stochastic nature of the ALP field.
