Abstract
According to the Multiple Point Principle our Universe is on the
coexistence curve of two or more phases of the quantum vacuum.
The coexistence of different quantum vacua can be regulated by the
exchange of the global fermionic charges between the vacua, such as
baryonic, leptonic or family charge. If the coexistence is regulated
by
the baryonic charge, all the coexisting vacua exhibit the baryonic
asymmetry.
Due to the exchange of the baryonic charge between the vacuum and
matter
which occurs above the electroweak transition, the baryonic asymmetry
of the
vacuum induces the baryonic asymmetry of matter in our
Standard-Model phase of the quantum vacuum. The present baryonic
asymmetry
of the Universe indicates that the characteristic energy scale which
regulates the equilibrium coexistence of different phases of quantum
vacua is
about 106 GeV.
