N2 - Recently a new baryogenesis mechanism proceeding via different particle and antiparticle capture rates by primordial black holes was suggested. Such a difference could appear due to interference between tree and one-loop scattering diagrams. The baryon number could be conserved at the particle interaction level. In present work the analogous leptogenesis mechanism is considered instead. The lepton asymmetry can be transferred into baryon sector through the electroweak processes that break both baryonic and leptonic numbers conservation but conserve B - L.
