Abstract content
We study the production of neutral Higgs boson pairs at $\gamma \gamma$ colliders through the $\gamma \gamma \to \phi_i\phi_j$ reaction within the context of the two-Higgs doublet model type III. Exact analytical expressions are presented. The use of a nonlinear $R_\xi$-gauge, which considerably simplifies the loop calculations and renders compact analytical expressions, is stressed. The $\gamma \gamma \to \phi_i\phi_j$ phenomenology is analyzed in the light of the most recent bounds obtained from precision measurements for the parameters of the model.
