  The $U_L(2)\bigotimes U_R(2) $ gauge model for the unified theory of the
electromagnetic and weak interactions which is free from a prior
self-interaction scalar field, is developed. Due to breaking the initial
symmetry the $SU_L(2)\bigotimes U_R(1) $ Lagrangian is derived. The obtained
$SU_L(2)\bigotimes U_R(1) $ Lagrangian contains the whole of terms
corresponding both to free boson and fermion fields and to interaction between
them, as it takes place in the Standard Model (SM) . We show that all boson
fields, including the Higgs one, directly arise due to breaking the initial
symmetry, and are generated by the initial gauge fields in contrary to the
Standard Model consideration. The Higgs fields are studied in detail. A broad
spectrum of states of the Higgs bosons is found. The masses of the Higgs
particle in such states are calculated.
