THE BIG BANG MODEL: ITS ORIGIN AND DEVELOPMENT

Odessa Astronomical Publications, 2017
The current Big Bang Model had its origin in Einstein's attempt to model a static cosmos, based on his general theory of relativity. Friedmann and Lemaitre, as well as de Sitter, further developed the model to cover other options, including nonstatic ...

Bounds on variations of the strange quark mass from Big Bang nucleosynthesis

Journal of High Energy Physics
We analyze the effect of a variation of the strange nucleon matrix element N m s s ¯ s N $$ \left\langle N|{m}_s\overline{s}s|N\right\rangle $$ on the abundances of the light elements produced in the Big Bang.

Updated Big Bang nucleosynthesis bounds on long-lived particles from dark sectors

Physics Letters B
As electromagnetic showers may alter the abundance of Helium, Lithium, and Deuterium, we can place severe constraints on the lifetime and amount of electromagnetic energy injected by long-lived particles.
