使用受 SNIa 和 CMB 观测约束的唯象本质模型讨论了与电磁耦合的本质标量场动力学驱动的精细结构常数 (α) 随时间变化的界限。我们发现那些允许早期精髓的模型在解耦时期给出了最大的变化Δα。此外，第五力实验表明Δα/α小于约0.1%。
The bound on the time variation of the fine structure constant (α) driven by the dynamics of quintessence scalar field which is coupled to electromagnetism is discussed using phenomenological quintessential models constrained by SNIa and CMB observations. We find that those models allowing early quintessence give the largest variation Δα at the decoupling epoch. Furthermore, the fifth force experiments imply that Δα/α is less than about 0.1%.
