A viable one-family technicolor model

We construct a one-family technicolor model which is consistent with the precision experiments on the electroweak interaction. The Majorana mass of the right-handed techni-neutrino is introduced and the techni-U(1)B-L symmetry is gauged to obtain the correct breaking of the electroweak symmetry. The tree-level kinetic mixing between the techni-U(1)B-L and U(1)Y gauge bosons plays an important role for having the consistent value of the S parameter.
