Author(s): Keisuke Inomata, Masahiro Kawasaki, and Yuichiro Tada We revisit the constraints on the small scale density perturbations ( 1 0 4 Mpc − 1 ≲ k ≲ 1 0 5 Mpc − 1 ) from the modification of the freeze-out value of the neutron-proton ratio at the big-bang nucleosynthesis era. Around the freeze-out temperature T ∼ 0.5 MeV , the universe can be divided into several local pa… [Phys. Rev. D 94, 043527] Published Tue Aug 23, 2016
