Abstract: We discuss the cosmic ray spectra in annihilating-decaying Nambu-Goldstonedark matter models. The recent observed positron-electron excesses at PAMELAand Fermi experiments are well fitted by the dark matter with a mass of 3TeVfor the annihilating model, while with a mass of 6 TeV for the decaying model.We also show that the Nambu-Goldstone dark matter models predict a distinctivegamma-ray spectrum in a certain parameter space.
