Estimation of a possible time variation of the electron mass from cmb observations

We study the e ects of a possible joint variation of the electron mass and the ne structure constant on the CMBR temper- ature uctuation spectrum. We use the rst-year WMAP (Bennet et al. 2003) data to estimate the values of the ne structure constant and of the electron mass at the decoupling time. ©...
