Multiverse as an ensemble of stable and unstable Universes


الملخص بالإنكليزية

Calculations performed within the Standard Model suggest that the electroweak vacuum is unstable if the mass of the Higgs particle is around 125 --- 126 GeV. Recent LHC results concerning the mass of the Higgs boson indicate that its mass is around 125.7 GeV. So it is possible that the vacuum in our Universe may be unstable. This means that it is reasonable to analyze properties of Universes with unstable vacua. We analyze properties of an ensemble of Universes with unstable vacua considered as an ensemble of unstable systems from the point of view of the quantum theory of unstable states and we try to explain why the universes with the unstable vacuum needs not decay.
