Tev we expect these objects influence the dynamics. Recently the indications in favor of this point of view were indeed found [@BVZ2007; @VZ2008; @Z2009].

In this paper we consider lattice realization of zero temperature Electroweak theory (without fermions). The phase diagram of the correspondent lattice model contains physical Higgs phase, where scalar field is condensed and gauge bosons $Z$ and $W$ acquire their masses. This physical phase is bounded by the phase transition surface. Crossing this surface one leaves the Higgs phase and enters the phase of the lattice theory, where the scalar field is not condensed.

In the lattice theory the ultraviolet cutoff is finite and is equal to the momentum ${\Lambda} = \frac{\pi}{a}$ (see, for example, [@UV]), where $a$ is the lattice spacing. The physical scale can be fixed, for example, using the value of the $Z$-boson mass $M^{\rm phys}_Z \sim 90$ GeV. Therefore the lattice spacing is evaluated to be $a \sim [90\,{\rm GeV}]^{-1} M_Z$, where $M_Z$ is the $Z$ boson mass in lattice units. Within the physical phase of the theory the lines of constant physics (LCP) are defined that correspond to constant renormalized physical couplings (the fine structure constant $\alpha$, the Weinberg angle $\theta_W$, and
