PPPC 4 DM secondary: A Poor Particle Physicist Cookbook for secondary radiation from Dark Matter

Abstract

We enlarge the set of recipes and ingredients at disposal of any poor particle physicist eager to cook up signatures from weak-scale Dark Matter models by computing two secondary emissions due to DM particles annihilating or decaying in the galactic halo, namely the radio signals from synchrotron emission and the gamma rays from bremsstrahlung. We consider several magnetic field configurations and propagation scenarios for electrons and positrons. We also provide an improved energy loss function for electrons and positrons in the Galaxy, including synchrotron losses in the different configurations, bremsstrahlung losses, ionization losses and Inverse Compton losses with an updated InterStellar Radiation Field.

25 pages, many figures. v2: a small clarification on the use of custom galactic magnetic fields added, matches version published on JCAP. All results are available at http://www.marcocirelli.net/PPPC4DMID.html
