A FORTRAN code for $\gamma \gamma \to ZZ$ in SM and MSSM

Abstract

Through the present paper, the code gamgamZZ is presented, which may be used to calculate all possible observables related to the process $\gamma \gamma \to ZZ$, in either the Standard Model (SM), or the minimal sypersymmetric standard model (MSSM) with real parameters.
