Abstract: The AMS-02 experiment is now measuring charged cosmic rays fluxes with an unprecedented precision. It is thus necessary to provide appropriate and complementary predictions for dark matter signals. To that end, computing electroweak corrections to the dark matter annihilation is an important task. It is particularly relevant for leptophilic models where anti-protons can be produced through the decay of massive gauge bosons. From the lack of particular spectral features in the AMS positron flux, we derive new model independent upper limits on the annihilation cross section. In particular we use a newly introduced background function that allows to set limits using all the energy spectrum probed by AMS-02. This is particularly interesting as important phenomena such as solar modulation take place at low energy. Using a new calculation of electroweak radiation for vector dark matter annihilation, we can predict the maximum flux of anti-protons in such leptophilic scenarios, to be compared with future AMS measurments.
