Quark and lepton masses in technicolor theories can be enhanced if the
high energy, extended technicolor (ETC) interactions play an important
role in electroweak symmetry breaking. This happens when the ETC coupling
and the technicolor gauge coupling at high energies lie
close to a certain
critical line. The enhancement has been associated with the existence of
composite scalars made mainly of technifermions, with
masses small compared to the ETC scale. The initial study of these states was
carried out with the technicolor gauge coupling
neglected. In this paper we investigate the properties of
such scalars including the technicolor gauge
interactions. We find that for realistic values of the gauge coupling, the
scalars will not be narrow resonances. Mass and
width estimates are made and some comments about the phenomenology of these
states are included.
