Big Bang Nucleosynthesis and Recombination

open access: yes, 2019
In this chapter we will describe Big Bang Nucleosynthesis (BBN), the combination of fundamental protons and neutrons into nuclei, as well as calculate more precisely the temperature of recombination.

Big Bang Nucleosynthesis with f(R) Gravity Scalarons and Astrophysical Consequences

open access: yesThe Astrophysical Journal
f ( R ) gravity is one of the serious alternatives of general relativity with a large range of astronomical consequences. In this work, we study Big Bang nucleosynthesis (BBN) in f ( R ) gravity theory.

Big Bang Nucleosynthesis: 2015

open access: yes, 2015
Big-bang nucleosynthesis (BBN) describes the production of the lightest nuclides via a dynamic interplay among the four fundamental forces during the first seconds of cosmic time. We briefly overview the essentials of this physics, and present new calculations of light element abundances through li6 and li7, with updated nuclear reactions and ...
