      abstract = {In a recent work, we emphasized that an excess in  trilepton events plus missing energy observed by the ATLAS  experiment at the LHC could be interpreted as a signal of  low-energy supersymmetry. In such a scenario the lightest  neutralino mass is approximately $m_χ≃60$ $GeV$ and the  direct dark matter detection cross section is naturally  below the current bound. In this work we present simple  extensions of this scenario that lead to an explanation of  the gamma-ray excess at the center of the Galaxy observed  by Fermi-LAT, as well as the antiproton excess observed by  AMS-02. These extensions include the addition of a small  $CP$-violating phase in the neutralino sector or the  addition of a light $CP$-odd Higgs scalar. Our study is of  special relevance in view of a recent analysis that casts  doubt on the previously accepted preference for millisecond  pulsars as the origin of the Galactic Center excess. },
