Abstract
The high precision of current and future CMB data may allow the detection of numerous physical processes that might change the standard model of recombination, leaving recognizable imprints on the angular power spectra. We review some of the results obtained in constraining the cariation of fundamental constants, in particular the effects of the gravitational constant G and of the fine structure constant α.
