Constraints on variation in α and m e from WMAP 7-year data
Aims. We update the constraints on the time variation of the fine structure constant α and the electron mass me, using the latest CMB data, including the 7-yr release of WMAP. Methods. We made statistical analyses of the variation of each one of the constants and of their joint variation, together w...
