Higgs mass to Z-boson mass ratio $\eta =
M_H/M_Z$). The points on LCP are parametrized by the lattice spacing. Our observation is that the LCP corresponding to realistic values of $\alpha$, $\theta_W$, and $\eta$ crosses the transition between the two “phases” at a certain value $a = a_c$ and for $a < a_c$ the scalar field is not condensed. We denote the corresponding value of the cutoff $\Lambda_c = \frac{\pi}{a_c}$. Our estimate for the considered values of the Higgs mass $M_H \sim 100, 160,
270$ Gev is $\Lambda_c = 1.4 \pm 0.2$ Tev (for the considered lattice sizes). We do not observe the dependence of $\Lambda_c$ on the lattice size. That’s why the value $\Lambda_c$ might appear as the maximal possible value of the cutoff allowed in the conventional Electroweak theory.

It is important to compare this result with the limitations on the Ultraviolet Cutoff, that come from the perturbation theory. From the point of view of perturbation theory the energy scale $1$ TeV appears in the Hierarchy problem [@TEV]. Namely, the mass parameter $\mu^2$ for the scalar field receives a quadratically divergent contribution in one loop. Therefore, the initial mass parameter ($\mu^2= - \lambda_c v^2$, where $v$ is the
