论文摘要
违反距离双重关系的行为直接与电磁细胞结构常数的时间变化有关。我们考虑了许多经过良好研究的$ f（t）$重力模型，并修改了其相应诱导违反距离二元关系的理论预测。我们通过精细结构恒定变化数据以及超新星数据和哈勃参数测量结果进一步提取涉及模型参数的约束。此外，我们限制了有效$ f（t）$引力常数的演变。最后，我们将经过修订的约束与电磁部门违反等价原理的现象学参数进行了比较。
A violation of the distance-duality relation is directly linked with a temporal variation of the electromagnetic fine-structure constant. We consider a number of well-studied $f(T)$ gravity models and we revise the theoretical prediction of their corresponding induced violation of the distance-duality relationship. We further extract constraints on the involved model parameters through fine-structure constant variation data, alongside with supernovae data, and Hubble parameter measurements. Moreover, we constrain the evolution of the effective $f(T)$ gravitational constant. Finally, we compare with revised constraints on the phenomenological parametrisations of the violation of the equivalence principle in the electromagnetic sector.
