We revisit the multi-component leptonically decaying dark matter (DM)scenario to explain the possible electron/positron excesses with the recentlyupdated AMS-02 data. We find that both the single- and two-component DM modelscan fit the positron fraction and $e^+/e^-$ respective fluxes, in ...
Dark mattercosmic raysAMS-02 experimentWe study the possible positron/electron excesses within the multi-component leptonically decaying dark matter (DM) scenario by fitting the most recent AMS-02 data on the positron fraction and total e+ + eu2212 flux. We show that both the single- and two...
the AMS-02single-photon mode, i.e. gamma ray photons revealed by the ECAL through electromagnetic shower production. By means of Monte Carlo simulations and Test Beam data, we present a preliminary approach to the gamma-ray photon selection procedure and discuss the potentiality of the detector....
The new AMS-02 leptonic data from 1 to 500 GeV are presented and discussed. These new data indicate that new sources of CR leptons need to be included to describe the observed spectra at high energies. Explanations of this anomaly may be found either in dark-matter particles annihilation or...
In addition to the AMS-02 data, we add HESS data to estimate the spectra of CR electrons and the diffuse gamma rays above TeV. In the conventional diffusion model, a global analysis is performed on the spectral features of CR electrons and the diffuse gamma rays by the GALRPOP package. ...
