The Mass of the Heavy Axion ${\eta }_6$

Abstract

If electroweak dynamical symmetry breaking is due to a chiral condensate of color sextet quarks, dynamics analagous to ``walking technicolor'' will enhance the condensate by orders of magnitude compared to the electroweak chiral scale. This enhancement compensates for the exponential suppression of electroweak scale color instanton interactions. As a result the ${\eta }_6$ axion can naturally aquire an electroweak scale mass.
