Cosmology with varying scales and couplings
arXiv:hep-ph/0302116 · doi:10.1142/9789812704498_0022
Abstract
The time variation of fundamental mass scales can have profound cosmological implications. We investigate a particular model of crossover quintessence which is compatible with all present cosmological observations. This model can also reconcile the reported time variation of the fine structure constant from quasar absorption lines with the bounds from archeo-nuclear physics and tests of the equivalence principle.
