vacuum average of the scalar field) should be set to infinity in such a way that the renormalized mass $\mu^2_R$ remains negative and finite. This is the content of the so-called fine tuning. It is commonly believed that this fine tuning is not natural [@TEV] and, therefore, one should set up the finite ultraviolet cutoff $\Lambda$. From the requirement that the one-loop contribution to $\mu^2$ is less than $10 |\mu_R^2|$ one derives that $\Lambda \sim 1$ TeV. However, strictly speaking, the possibility that the mentioned fine tuning takes place is not excluded.

In the perturbation theory there is also more solid limitation on the Ultraviolet cutoff. It appears as a consequence of the triviality problem, which is related to Landau pole in scalar field self coupling $\lambda$ and in the fine structure constant $\alpha$. The Landau pole in fine structure constant is related to the fermion loops and, therefore, has no direct connection with our lattice result (we neglect dynamical fermions in our consideration). Due to the Landau pole the renormalized $\lambda$ is zero, and the only way to keep it equal to its measured value is to impose the limitation on the cutoff. That’s why the Electroweak theory is
