Abstract
We assume the excess e+/(e+ +e−) in AMS-02 data comes from annihilations of dark matter and try to interpret the data by Inert Higgs Doublet Model. We calculate the e ± flux with MicrOMEGAs code and use χ 2 to describe the goodness of fitting. We scan the parameter space : the masses of the Z 2 symmetry odd particles are between 500 GeV and 12000 GeV. However, we don’t have any points can reach 95% CL and the minimal χ 2 which we get is 7.59×10 1 . In summary, the inert Higgs Doublet Model parameter space is disfavored by AMS-02 e+/(e+ +e−) data when the masses of the Z 2 symmetry odd particles are smaller than 12000 GeV.
