AbstractIn the light of the latest measurements on the total e(+) + e(-) flux by CALET and DAMPE experiments, we revisit the multicomponent leptonically decaying dark matter (DM) explanations to the cosmic-ray electron/positron excesses observed previously. Especially, we use the single and double-component DM models to explore the compatibility of the AMS-02 positron fraction with the new CALET or DAMPE data. As a result, for either the AMS-02 + CALET dataset or the AMS-02 + DAMPE one, both the single and double-component DM models can provide reasonable fits. If we further take into the diffuse gamma-ray constraints from Fermi-LAT, only the double-component DM models are allowed. (C) 2020 The Author(s). Published by Elsevier B.V.
