PPPC 4 DM ID: a poor particle physicist cookbook for dark matter indirect detection
Abstract
We provide ingredients and recipes for computing signals of TeVscale Dark Matter annihilations and decays in the Galaxy and beyond. For each DM channel, we present the energy spectra of at production, computed by highstatistics simulations. We estimate the Monte Carlo uncertainty by comparing the results yielded by the Pythia and Herwig event generators. We then provide the propagation functions for charged particles in the Galaxy, for several DM distribution profiles and sets of propagation parameters. Propagation of e^{±} is performed with an improved semianalytic method that takes into account positiondependent energy losses in the Milky Way. Using such propagation functions, we compute the energy spectra of e^{±},bar p and bar d at the location of the Earth. We then present the gamma ray fluxes, both from prompt emission and from Inverse Compton scattering in the galactic halo. Finally, we provide the spectra of extragalactic gamma rays. All results are available in numerical form and ready to be consumed.
