【 摘 要 】

We present the results of a combined analysis of the whole set of AMS-02 electrons and positrons data conducted in a self-consistent framework in which a theoretical modeling of all the components that can contribute to the observed fluxes is realized. We study the main features of the electron/positron emission from primary and secondary astrophysical sources, as well as from dark matter annihilation/decay processes, with the purpose of assessing a way to disentangle a possible dark matter signal from a loosely known astrophysical background. Then, we investigate the conditions under which a good agreement between theoretical predictions and experimental measurements can be achieved, with a particular focus on the constraints that can be derived on dark matter properties.
