WMAP 5-year constraints on time variation of α and m<sub>e</sub> in a detailed recombination scenario
We study the role of fundamental constants in an updated recombination scenario. We focus on the time variation of the fine structure constant α, and the electron mass m<sub>e</sub> in the early Universe, and put bounds on these quantities by using data from CMB including WMAP 5-yr relea...
