Dark matter production from two evaporating PBH distributions

Particulate dark matter (DM), completely isolated from the Standard Model particle sector, can be produced in early Universe primordial black hole (PBH) evaporation. However, big bang nucleosynthesis (BBN) observations put an upper bound on initial mass of PBH requiring to evaporate before advent BBN. DM particles range $\ensuremath{\sim}(1--{10}^{9})\text{ }\text{ }\mathrm{GeV}$ cannot explain observed relic abundance for dominated universe due this BBN constraint. assumes presence only one monochromatic distribution Universe. In work, we explore simple possibility achieving with masses above mentioned era two evaporating distributions and demonstrate that fermionic consistent change slightly.
