AMS02 is a multi-purpose spectrometer with superconducting magnet, designed for 3 years of data taking abroad the International Space Station. Its high performance regarding particle identification and energy measurement will allow performing indirect searches for dark matter (DM) in different channel simultaneously: gamma rays, positrons, antiprotons and hopefully antideuterons. A new...

The excess of diffuse galactic gamma rays above 1 GeV, as observed by the EGRET telescope on the NASA Compton Gamma Ray Observatory, shows all the key features from Dark Matter (DM) annihilation: 1) the energy spectrum of the excess is the same in all sky directions and is consistent with the gamma rays expected for the annihilation of WIMPs with a mass between 50-100...

Recently it was shown that the excess of diffuse Galactic gamma rays above 1 GeV could be interpreted as a Dark Matter annihilation signal. From the spectral shape of the excess it is possible to determine a range for the allowed WIMP mass which can be used to test the supersymmetric parameter space. It is found that the EGRET excess combined with electroweak and other constraints, e.g....

The excess above 1 GeV in the energy spectrum of the diffuse galactic gamma radiation, measured with the EGRET experiment, can be interpreted as the annihilation of dark matter (DM) particles. The DM is distributed in a halo around the Milky Way. From the directionality of the gamma ray excess it is possible to determine the halo profile. A comparison is made between the theoretical...

245. Uncertainties of the antiproton flux from dark matter annihilation in comparison with the EGRET excess of diffuse gamma rays

Parallel Talk

The EGRET excess of diffuse Galactic gamma rays shows all the features expected from dark matter annihilation (DMA): a spectral shape given by the fragmentation of mono-energetic quarks, which is the same in all sky directions and an intensity distribution of the excess expected from a standard dark matter halo, predicted by the rotation curve. From the EGRET excess one can predict the...

147. The anomaly in the cosmic ray positron spectrum

A recent analysis of cosmic ray data from a space borne experiment by the AMS collaboration confirms the excess in the cosmic ray positron spectrum observed by previous balloon experiments. The combination of the various experimental data establishes a deviation from the expected background with a significance of more than four standard deviations. The observed change in the spectral index...
