从加速宇宙中预期的精细结构常数的可能的时间变化

Possible time-variability of the fine-structure constant expected from the accelerating universe

Yasunori Fujii

摘要:

我们给出了精细结构常数随时间变化的理论计算,以拟合最近对类星体吸收线测量的精确分析结果。我们发现标量张量理论的参数和初始值要比拟合加速的宇宙本身精确得多,但导致不容易检测到的暗能量的状态方程在早期的时代的影响。

英文摘要:

We present a theoretical calculation on the time-variability of the fine-structure constant to fit the result of the recent precise analysis of the measurement of the QSO absorption lines. We find the parameters and initial values of the scalar-tensor theory to be determined much more accurately than fitting the accelerating universe itself, but leading not to easy detections of the effect on the equation of state of the dark energy in the earlier epochs.
