Solving puzzles of GW150914 by primordial black holes
  The black hole binary properties inferred from the LIGO gravitational wave
signal GW150914 posed several serious problems. The high masses and low
effective spin of black hole binary can be explained if they are primordial
(PBH) rather than the products of the stellar binary evolution. Such PBH
properties are postulated ad hoc but not derived from fundamental theory. We
show that the necessary features of PBHs naturally follow from the slightly
modified Affleck-Dine (AD) mechanism of baryogenesis. The log-normal
distribution of PBHs, predicted within the AD paradigm, is adjusted to provide
an abundant population of low-spin stellar mass black holes. The same
distribution gives a sufficient number of quickly growing seeds of supermassive
black holes observed at high redshifts and may comprise an appreciable fraction
of Dark Matter which does not contradict any existing observational limits.
Testable predictions of this scenario are discussed.
