Abstract:We present a complete one-loop study of the process $gamma gamma to {tilde chi}^0_i {tilde chi}^0_j$ and the predicted cross section in a $gamma gamma $ 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 ${tilde chi}^0_i {tilde chi}^0_j to gammagamma$ 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.Received: 6 November 2003, Published online: 9 January 2004Programme drsquoActions Intégrées Franco-Hellenique, Platon 04100 UM.
