Electroweak Theory without Higgs Boson

We present a new formulation for the bosonic sector of the Electroweak Model with the 3-dimensional spherical geometry in the target space. The free lagrangian in the spherical field space along with the standard gauge fields lagrangian form the full higgsless lagrangian of the model, which second order terms reproduce the same fields with the same mass as the Standart Electroweak Model. The vector bosons mass are generated automatically, so there is no need in special mechanism like spontaneous symmetry breaking.
