Description

We study the Baryon-Dark Matter Coincidence Problem with primordial black holes (PBHs). PBHs induce baryogenesis through the Baumann-Steinhardt-Turok mechanism, by Hawking evaporating into a beyond-Standard Model particle $X$ that has baryon number and CP-violating couplings to the Standard Model. Dark matter is also produced in our mechanism. The gravitational wave signatures are presented, and a UV completion is discussed.
