Big Bang nucleosynthesis, matter-antimatter regions, extra relativistic species, and relic gravitational waves
Massimo Giovannini, Elina Keihanen, Hannu Kurki-Suonio
Provided that matter-antimatter domains are present at the onset of big bang nucleosynthesis (BBN), the number of allowed additional relativistic species increases, compared to the…
