Cosmological solutions to the Lithium problem: Big-bang nucleosynthesis with photon cooling, -particle decay and a primordial magnetic field
Dai G. Yamazaki, Motohiko Kusakabe, Toshitaka Kajino +2
The Li abundance calculated in BBN with the baryon-to-photon ratio fixed from fits to the CMB power spectrum is inconsistent with the observed lithium abundances on the surface…
General limit on the relation between abundances of D and Li in big bang nucleosynthesis with nucleon injections
Motohiko Kusakabe, Myung-Ki Cheoun, K. S. Kim
The injections of energetic hadrons could have occurred in the early universe by decays of hypothetical long-lived exotic particles. The injections induce the showers of nonthermal…
Revised Big Bang Nucleosynthesis with long-lived negatively charged massive particles: updated recombination rates, primordial 9Be nucleosynthesis, and impact of new 6Li limits
Motohiko Kusakabe, K. S. Kim, Myung-Ki Cheoun +3
We extensively reanalyze effects of a long-lived negatively charged massive particle, X-, on big bang nucleosynthesis (BBN). The BBN model with an X- particle was originally motiva…
