Updated Big Bang nucleosynthesis bounds on long-lived particles from dark sectors
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. Considering up-to-date measurements of the light element abundances that point to Yp=0.245±0.00...
