Creation of Particles and Entropy in the Early Friedmann Universe

Cold Dark Matter and Primordial Superheavy Particles

“…As it is known [4] creation of superheavy particles with the mass of the order of the Grand Unification scale with the subsequent decays of its short living component on quarks and leptons with baryon charge and CP -nonconservation can lead to explanation of the observable matter. In Refs.…”

Active galactic nuclei and transformation of dark matter into visible matter

“…where b (0) ≈ 5.3 × 10 −4 for scalar and b (1/2) ≈ 3.9 × 10 −3 for spinor particles. It occurs that N ∼ 10 80 for M ∼ 10 14 GeV [6]. The radiation dominance at the end of inflation era for dark matter is important for our calculations.…”

“…In our previous papers [2] we tried to explain these events by the hypothesis investigated by us [3] and some other authors [4] that dark matter consists mainly of neutral stable superheavy particles with masses of the order of the Grand Unification (GU) scale M U = 10 14 − 10 15 GeV. The argument for this was due to numerical estimate obtained earlier [5,6] that gravitation of the early expanding Universe could produce the observable number of visible particles (the Eddington number) if it first created from vacuum superheavy particles which then decayed into visible ones but part of them survived till today as dark matter.…”

Graviatom of superheavy dark matter as a source of gravitational radiation

“…There are several theoretical models that provide a set of possible candidates for the role of dark matter [1], [2], [3]. Also in the article [4], a hypothesis was proposed that particles of dark matter are neutral, scalar, superheavy particles with the mass of the order of Grand Unification 10 15 GeV. Similar ideas were considered later in [5].…”
