Low-lying Resonances and Relativistic Screening in Big Bang Nucleosynthesis
Abstract
We explore effects of the screening due to the relativistic electron-positron plasma and presence of resonances in the secondary reactions leading to A=7 nuclei during the Big Bang Nucleosynthesis. In particular, we investigate and examine possible low-lying resonances in the Be(He, )C reaction and examine the resultant destruction of Be for various resonance locations and strengths. While a resonance in the C compound nucleus is thought to have negligible effects we explore the possibility of an enhancement from plasma screening that may adjust the final Be abundance. We find the effects of relativistic screening and possible low-lying resonances to be relatively small in the standard Early Universe models.
