Early Universe Constraints on Time Variation of Fundamental Constants
Susana J. Landau, Mercedes E. Mosquera, Claudia G. Scoccola +1
We study the time variation of fundamental constants in the early Universe. Using data from primordial light nuclei abundances, CMB and the 2dFGRS power spectrum, we put constraint…
Time variation of the electron mass in the early universe and the Barrow-Magueijo model
Claudia G. Scóccola, Mercedes E. Mosquera, Susana J. Landau +1
We put limits on the time variation of the electron mass in the early universe using observational primordial abundances of D, He4 and Li7, recent data from the Cosmic Microwave Ba…
Testing Primordial Abundances With Sterile Neutrinos
O. Civitarese, M. E. Mosquera
The mixing between sterile and active neutrinos is taken into account in the calculation of Big Bang Nucleosynthesis. The abundances of primordial elements, like D, 3He, 4He and 7L…
Time variation of the fine structure constant in the early universe and the Bekenstein model
Mercedes E. Mosquera, Claudia G. Scoccola, Susana J. Landau +1
We calculate bounds on the variation of the fine structure constant at the time of primordial nucleosynthesis and at the time of neutral hydrogen formation. We use these bounds and…
