Abstract：
The Yukawa corrections from the pseudo-Goldstone bosons (PGBs) in the one generation technicolor (OGTC) model to the process γγ→b are calculated. We find the corrections from the PGBs to the cross section γγ→b are more than 10% in the certain parameter values region. The maximum of the relative corrections to the process e ⁺e ^－→γγ→b may reach －51% in laser back scattering photos mode,and is only －17.9% in beamstrahlung photons mode. The corrections are greatly larger the contributions from the relevant particles in the standard model and the supersymmetric model. It can be considered as a signatures of finding the technicolor at the next-generation high energy photons collision.
