Time-evolution of the fine-structure constant in runaway dilaton models

P. E. Vielzeuf, C. J. A. P. Martins

Abstract
We study the detailed time-evolution of the fine-structure constant α in the string- inspired runaway dilaton class of models of Damour, Piazza and Veneziano [1, 2]. We provide constraints on this scenario via the time-variations of the fine-structure constant α as measured by spectroscopic experiments and we explore ways to distinguish the dilaton runaway models from other alternative.
