Big bang nucleosynthesis constraints on bulk neutrinos
H. S. Goh, R. N. Mohapatra
Abstract
We examine the constraints imposed by the requirement of successful big bang nucleosynthesis on models with one large extra dimension and a single bulk neutrino. We solve the Boltzman kinetic equations for the thermal distribution of bulk neutrino modes and evaluate their contribution to the energy density of the universe at the BBN epoch. This helps us to constrain the size of the extra dimensions and the mixing parameter between the active and bulk neutrinos.
