Cosmic Antiprotons from Neutralino Annihilation in the Galactic halo
G. Mignola
We investigate the possibility that the antiproton-to-proton flux ratio which is measured in cosmic rays may be generated by neutralino-neutralino annihilation in the galactic halo…
Perspectives for Detection of a Higgsino-like Relic Neutralino
A. Bottino, N. Fornengo, G. Mignola +2
It has been conjectured by Ambrosanio, Kane, Kribs, Martin and Mrenna (AKM) that the CDF event is due to a decay chain involving two neutrali…
On neutralino stars as microlensing objects
V. Berezinsky, A. Bottino, G. Mignola
The microlensing objects, Machos, recently observed in the halo of our Galaxy, can be interpreted as dense neutralino objects, neutralino stars, produced by the gravitational insta…
Galactic diffusion and the antiprotron signal of supersymmetric dark matter
P. Chardonnet, G. Mignola, P. Salati +1
The leaky box model is now ruled out by measurements of a cosmic ray gradient throughout the galactic disk. It needs to be replaced by a more refined treatment which takes into acc…
Non--Baryonic Dark Matter
V. Berezinsky, A. Bottino, G. Mignola
The best particle candidates for non--baryonic cold dark matter are reviewed, namely, neutralino, axion, axino and Majoron. These particles are considered in the context of cosmolo…
