Abstract

We consider two scalar fields interacting through a ${\chi }^{\ast }\chi {\varphi }^{\ast }\varphi$ term in the presence of a Reissner–Nordstrøm black hole. Initially, only $\chi$ particles are present. We find that the produced $\varphi$ particles are localized in a region around the black hole and have a tendency toward condensation provided that $\varphi$ particles are much heavier than the $\chi$ particles. We also find that such a configuration is phenomenologically viable only if the scalars and the black hole have dark electric charges.
