Query: False vacuum as an unstable state: possible cosmological implications   Recent LHC results concerning the mass of the Higgs boson indicate that the
vacuum in our Universe may be unstable. We analyze properties of unstable
vacuum states from the point of view of the quantum theory of unstable states.
From the literature it is known that some of false vacuum states may survive up
to times when their survival probability has a non-exponential form. At times
much latter than the transition time, when contributions to the survival
probability of its exponential and non-exponential parts are comparable, the
survival probability as a function of time $t$ has an inverse power-like form.
We show that at this time region the instantaneous energy of the false vacuum
states tends to the energy of the true vacuum state as $1/t^{2}$ for $t \to
\infty$. Properties of the instantaneous energy at transition times are also
analyzed for a given model. It is shown that at this time region large and
rapid fluctuations of the instantaneous energy take place. This suggests
analogous behavior of the cosmological constant at these time regions.
