A Top Quark Soliton and its Anomalous Chromomagnetic Moment
We show that under the assumption of dynamical symmetry breaking of electro
weak interactions by a top quark condensate, motivated by the Top Mode Standard
Model, the top quark in this effective theory can be considered then as chiral
color soliton (qualiton). This is realized in an effective four-fermion
interaction with chiral as well as symmetry.
In the pure top sector the qualiton consists of a top valence quark and a Dirac
sea of top and anti-top quark coupled to a color octet of Goldstone pions. The
mass spectra, isoscalar quadratic radii and the anomalous chromomagnetic moment
due to a non-trivial color form factor are calculated with zero and finite
current top masses and effects at the Hadron Colliders are discussed. The
anomalous chromomagnetic moment turns out to have a value consistent with the
top production rates of the D0- and CDF-measurements.Comment: LaTeX, using RevTeX.sty and aps.sty, without figures, 16 pages, to be
