英文摘要: With the accurate cosmic ray (CR) electron and positron spectra (denoted as Phi(e-) and Phi(e+), respectively) measured by AMS-02 Collaboration, the difference between the electron and positron fluxes (i.e., Delta Phi = Phi(e-) - Phi(e+)), dominated by the propagated primary electrons, can be reliably inferred. In the standard model, the spectrum of propagated primary CR electrons at energies = 30 GeV softens with the increase of energy. The absence of any evidence for such a continuous spectral softening in Delta Phi strongly suggests a significant 'excess' of primary CR electrons and at energies of 100-400 GeV the identified excess component has a flux comparable to that of the observed positron excess. Middle-age but 'nearby' supernova remnants (e.g., Monogem and Geminga) are favored sources for such an excess. (C) 2015 The Authors. Published by Elsevier B.V.
