Time variation of the electron mass in the early universe and the barrow-magueijo model

Mostrar todas las versiones(3)

We put limits on the time variation of the electron mass in the early universe using observational primordial abundances of D, 4He, and 7Li, recent data from the cosmic microwave background, and the 2dFGRS power spectrum. Furthermore, we use these constraints together with other astronomical and geo...
