Description
The 1-loop computation of the processes $\tchi_i \tchi_j \to \gamma Z$ has been
performed at an arbitrary c.m. energy for any pair of MSSM neutralinos. As an
application suitable for Dark
Matter (DM) searches, the neutralino-neutralino annihilation is studied at the limiting
case of vanishing relative velocity, describing the present DM distribution in the
galactic
halo; and at a relative velocity of about 0.5, determining the neutralino relic density
contributions. Our results are contained in the FORTRAN code PLATONdmgZ, applying to
any set
of real MSSM parameters. Numerical results are also presented for a sample of 6 MSSM
models,
describing the various possible neutralino properties. A comparison with other existing
works is also made.
