Electroweak light from Dark Matter annihilation

Friday January 21st 14:30hs - Seminar room

Speaker: Alfredo Urbano (INFN & Univ. of Salento, Lecce, & IFAE, Barcelona)

Abstract:

The computation of the energy spectra of Standard Model particles originated from the annihilation/decay of dark matter particles is of primary importance in indirect searches of dark matter.

We compute how the inclusion of electroweak corrections significantly alter such spectra when the mass M of dark matter particles is larger than the electroweak scale: soft electroweak gauge bosons are copiously radiated opening new channels in the final states which otherwise would be forbidden if such corrections are neglected. We discuss about these model-independent effects.
