Impacts of Hawking Radiation from Primordial Black Holes in Critical Collapse Model on the Light Element Abundances
Yudong Luo, Chao Chen, Motohiko Kusakabe +1
We study the photodisintegration process triggered by the nonthermal electromagnetic Hawking radiation from primordial black holes (PBHs) in critical collapse model. We consider th…
Nuclear Reaction Screening, Weak Interactions, and r-Process Nucleosynthesis in High Magnetic Fields
Michael Famiano, A. Baha Balantekin, Toshitaka Kajino +3
Coulomb screening and weak interactions in a hot, magnetized plasma are investigated. Coulomb screening is evaluated in a relativistic thermal plasma in which electrons and positro…
Screening corrections to Electron Capture Rates and resulting constraints on Primordial Magnetic Fields
Yudong Luo, Michael A. Famiano, Toshitaka Kajino +2
We explore screening effects arising from a relativistic magnetized plasma with applications to Big Bang nucleosynthesis (BBN). %Specifically, due to their small magnetic moments,…
Cosmological Solutions to the Lithium Problem
G. J. Mathews, A. Kedia, N. Sasankan +6
The abundance of primordial lithium is derived from the observed spectroscopy of metal-poor stars in the galactic halo. However, the observationally inferred abundance remains at a…
Big Bang Nucleosynthesis with an Inhomogeneous Primordial Magnetic Field Strength
Yudong Luo, Toshitaka Kajino, Motohiko Kusakabe +1
We investigate the effect on the Big Bang Nucleosynthesis (BBN) from the presence of a stochastic primordial magnetic field (PMF) whose strength is spatially inhomogeneous. We assu…
On the relative velocity distribution for general statistics and an application to big-bang nucleosynthesis under Tsallis statistics
Motohiko Kusakabe, Toshitaka Kajino, Grant J. Mathews +1
The distribution function of the relative velocity in a two-body reaction of nonrelativistic uncorrelated particles is derived for general cases of given distribution functions of…
