Description
We present a complete 1-loop study of the process $γγ\to \tchi^0_i \tchi^0_j$ and the predicted cross section in a $γγ$ Linear Collider. A suitable numerical code PLATONlc, valid for any set of real MSSM parameters, is released. This study and code are complementary to those suitable for Dark Matter detection through the inverse process $\tchi^0_i \tchi^0_j \to γγ$ describing neutralino-neutralino annihilation at rest, which were presented previously. If SUSY is realized in Nature, both codes should be very helpful in future astrophysical and collider studies of the neutralino sector.
