英文摘要	Primordial black holes (PBHs), which could be naturally produced in the early universe, remain a promising dark matter candidate. They can merge with a supermassive black hole (SMBH) at the center of a galaxy and generate a gravitational wave (GW) signal in the favored frequency region of laser interferometer space antenna (LISA)-like experiments. In this study, we investigated the event rate calculation for extreme mass ratio inspirals and the sensitivities of various proposed GW detectors. We determined that such experiments offer a novel and effective tool for testing scenario where PBHs constitute (a fraction of) dark matter. The PBH energy density fraction of dark matter (f(PBH)) can potentially be explored for values as small as 10(-3)-10(-4). Further the LISA can search for PBH masses up to 10(-2)-10(-1) M-circle dot. Other proposed GW experiments can investigate lower PBH mass regimes.
