Primordial black holes and scotogenic dark matter

Authors: Teruyuki Kitabayashi;

Primordial black holes and scotogenic dark matter

Abstract

We study the effect of the scotogenic dark matter on the primordial black holes (PBHs) and vice versa. We show that if the PBHs evaporate in the radiation dominant era, the upper limit of the initial mass of the PBHs $M_{\rm in}$ should be constrained as $10^4 \lesssim M_{\rm in}/M_{\rm Pl} \lesssim 10^{10}$ for $\mathcal{O}$(1) TeV scotogenic dark matter ($\mathcal{O}$(1) TeV is the most appropriate energy scale in the scotogenic model). On the other hand, if the PBHs evaporate in the PBH dominated era, a quite heavy scotogenic dark matter ($m_{/rm DM} /gtrsim 10^9$ GeV) for $M_{/rm in}/M_{/rm Pl} /sim 10^{13}$ may be allowed.
