| « Two observables for indirect DM detection: CMB and thermal neutrinos from the Sun » |

F. Iocco |
| In this twofold seminar I will first address how self-annihilating (or decaying) DM should leave an imprint on the CMB power-spectra, thus making it an interesting observable for DM detection, or, in absence of any signal an exquisite tool for model constraining (self-annihilation cross section/lifetime). In the second part I will address the effect that Weakly Interacting DM particles have on the structure of the Sun, and how this should result in a modification of thermal, nuclearly procuced neutrinos. This makes the 8B neutrino flux at Earth an observable for WIMP DM model constraining (spin dependent elastic scattering cross section). |
