Baryon-number conservation in Bose-Einstein condensate black holes

Primordial black holes are studied in the Bose-Einstein condensate description of space-time. The question of baryon-number conservation is investigated with emphasis on the possible formation of bound states of the system's remaining captured baryons. This leads to distinct predictions both for the formation time, which for the naively natural assumptions is shown to lie between 10^-12 s and 10¹² s after the big bang, and for the remnant's mass, yielding approximately 3×10²³ kg in the same scheme. The consequences for astrophysically formed black holes are also considered.
