Query: Scenario of baryogenesis   Scenario of baryogenesis is considered in which primordial plasma starting
from the Planck scale consists of primordial particles being the precursors of
electrons and clusters of particles being the precursors of protons.
Equilibrium between the precursors of protons and the precursors of electrons
is defined by the proton-electron mass difference. At the temperature equal to
the mass of electron, primordial particles transit into protons, electrons,
photons.
