Abstract
We derive and solve the compositeness condition for the SU(N_c) gauge boson at the next-to-leading order in 1/N_f (N_f is the number of flavors) and the leading order in ln(\Lambda ^2) (\Lambda is the compositeness scale) to obtain an expression for the gauge coupling constant in terms of the compositeness scale. It turns out that the argument of gauge-boson compositeness (with a large \Lambda) is successful only when N_f/N_c>11/2, in which the asymptotic freedom fails.
