Three-body exchanges with primordial black holes

Sinha, Kuver; Bhalla, Badal; Lehmann, Benjamin V. +1 more

The abundance of massive primordial black holes has historically been constrained by dynamical probes. Since these objects can participate in hard few-body scattering processes, they can readily transfer energy to stellar systems and, in particular, disrupt wide binaries. However, disruption is not the only possible outcome of such few-body proces…
