$\Delta \alpha /\alpha$ from QSO absorption lines driven by an oscillating scalar field

Abstract

The new result on the QSO absorption lines from VLT-UVES sample is compared with the past reports on the time-variability of the fine-structure "constant" derived from the Keck/HIRES observation, on the basis of an oscillatory behavior of the scalar field supposed to be responsible for the cosmological acceleration.
