Query: Top-Bottom Splitting in Technicolor with Composite Scalars   We present a model of dynamical electroweak symmetry breaking in which the
splitting between the top and bottom quark masses arises naturally. The W and Z
masses are produced by a minimal technicolor sector, the top quark mass is
given by the exchange of a weak-doublet technicolored scalar, and the other
quark and lepton masses are induced by the exchange of a weak-doublet
technicolor-singlet scalar. We show that, in the presence of the latter scalar,
the vacuum alignment is correct even in the case of SU(2) technicolor. The fit
of this model to the electroweak data gives an acceptable agreement
(chi-squared = 28 for 20 degrees of freedom). The mass hierarchy between the
standard fermions other than top can also be explained in terms of the
hierarchy of squared-masses of some additional scalars. We discuss various
possibilities for the compositeness of the scalars introduced here.
