Abstract
By solving the compositeness condition, under which the Yukawa-type model coincides the NJL type model, we obtain the expressions for the effective coupling constants in terms of the compositeness scale at the next-to-leading order in 1/N. In the NJL model with a scalar composite, the next to leading contributions are too large for N_c=3. In the induced gauge theory with abelian gauge symmetry, the correction term is reasonably suppressed, while in the non-abelian gauge theory the corrections are suppressed only when it is asymptotically non-free.
