Abstract

Exotic quarks belonging to 6, 8, 10, or higher representations of $SU {(3)}_{c}$ (quantum chromodynamics) naturally interact more strongly than conventional 3-plet quarks. Therefore, chiral-symmetry breaking in exotic quark sectors may occur at much larger mass scales than ordinary chiral-symmetry breaking. If those mass scales are about $10^{3}$ times larger, then when appended to the Weinberg-Salam model exotic quark-antiquark bound-state condensates could dynamically break the flavor SU(2) × U(1) gauge symmetry and produce viable $W^{\pm}$ and $Z^{0}$ masses which satisfy $M_{W} = M_{Z} {cos θ}_{W}$ . Features of this scenario are described.
