Cosmic-ray antiprotons from neutralino annihilation into gluons.

چکیده
We estimate the ux of cosmic-ray antiprotons expected from the annihilation of neutralinos in the galactic halo. The antiproton signal may ooer an important alternative detection scheme in the case that neutralino annihilation proceeds mainly to the two-gluon nal state.

Neutralino annihilation into gluons.
We present a complete calculation of the cross section for neutralino annihilation into the two-gluon final state. This channel can be quite important for the phenomenology of neutralino annihilation due to the well-known helicity suppression of neutralino annihilation into light quarks and leptons. In addition, we calculate the cross section for annihilation of neutralinos into a gluon and qua...
متن کاملCosmic–ray Antiprotons from Neutralino Annihilation in the Halo
We report the main results of a paper where recent data of low–energy cosmic–ray p̄ spectrum have been analyzed in terms of newly calculated fluxes for secondary antiprotons and for a possible contribution of an exotic signal due to neutralino annihilation in the galactic halo. We also present the results of a paper in which we have proved that a sizeable fraction of the supersymmetric neutralin...
متن کاملEXOTIC MATTER RESEARCH IN SPACE Rom2F/2001/06
The direct detection of annihilation products in cosmic rays offers an alternative way to search for dark matter particles candidates. Here we will see in particular that the study of the spectrum of antiproton and positrons offers good possibilities to perform this search and we will review our experimental effort in this direction. 1 Probing for dark matter with cosmic rays space experiments ...
متن کاملCosmic antiprotons as a probe for supersymmetric dark matter?
The flux of cosmic ray antiprotons from neutralino annihilations in the galactic halo is computed for a large sample of models in the MSSM (the Minimal Supersymmetric extension of the Standard Model). We also revisit the problem of estimating the background of low-energy cosmic ray induced secondary antiprotons, taking into account their subsequent interactions (and energy loss) and the presenc...
