摘要:

寻求一个可能的解释,最近的数据表明银河系内的电子-质子质量比的时空变化,我们考虑一个唯象模型,其中的有效费米子质量依赖于当地的外尔张量的值。我们对比所需的模型的自由参数的值与边界从现代测试的弱等价原理的违反,我们发现,这些数量是不相容的。这一结果表明,核子和电子质量通过与Weyl张量的耦合而变化不是一个可行的模型。

英文摘要:

Seeking a possible explanation for recent data indicating a space-time variation of the electron-to-proton mass ratio within the Milky Way, we consider a phenomenological model where the effective fermion masses depend on the local value of the Weyl tensor. We contrast the required values of the model's free parameters with bounds obtained from modern tests on the violation of the Weak Equivalence Principle and we find that these quantities are incompatible. This result indicates that the variation of nucleon and electron masses through a coupling with the Weyl tensor is not a viable model.
