Scientific paper

We have studied the effects on the gamma-ray flux on Earth by neutralino annihilations in caustic rings of dark matter in the Galactic halo. The caustic ring model by Sikivie has been used where dark matter particles are assumed to possess angular momentum with respect to the Galactic centre. The computer code DarkSUSY was then used to examine the supersymmetric implications on the flux. We conclude that a small signal might be detectable under very optimistic assumptions, but under these only.
