Abstract
In order to reveal the nature of dark matter, it is crucial to detect its non-gravitational interactions with the standard model particles. The traditional dark matter searches focused on the so-called weakly interacting massive particles. [...]

Strongest model-independent bound on the lifetime of Dark Matter
/ Audren, Benjamin (ITPP, Lausanne) ; Lesgourgues, Julien (ITPP, Lausanne ; CERN ; Annecy, LAPTH) ; Mangano, Gianpiero (INFN, Naples) ; Serpico, Pasquale Dario (Annecy, LAPTH) ; Tram, Thomas (ITPP, Lausanne)
Dark Matter is essential for structure formation in the late Universe so it must be stable on cosmological time scales. But how stable exactly? Only assuming decays into relativistic particles, we report an otherwise model independent bound on the lifetime of Dark Matter using current cosmological data. [...]

Bremsstrahlung gamma rays from light Dark Matter
/ Cirelli, Marco (IPhT, Saclay) ; Serpico, Pasquale D. (Annecy, LAPTH) ; Zaharijas, Gabrijela (ICTP, Trieste)
We discuss the often-neglected role of bremsstrahlung processes on the interstellar gas in computing indirect signatures of Dark Matter (DM) annihilation in the Galaxy, particularly for light DM candidates in the phenomenologically interesting O(10) GeV mass range. Especially from directions close to the Galactic Plane, the expected gamma-ray spectrum is altered via two effects: directly, by the photons emitted in the bremsstrahlung process on the interstellar gas by energetic electrons which are among the DM annihilation byproducts; indirectly, by the modification of the same electron spectrum, due to the additional energy loss process in the diffusion-loss equation (e.g. [...]

Gamma ray constraints on Decaying Dark Matter
/ Cirelli, Marco (CERN ; Saclay) ; Moulin, Emmanuel (Saclay) ; Panci, Paolo (Southern Denmark U., CP3-Origins) ; Serpico, Pasquale D. (Annecy, LAPTH ; CERN) ; Viana, Aion (Saclay)
We derive new bounds on decaying Dark Matter from the gamma ray measurements of (i) the isotropic residual (extragalactic) background by Fermi and (ii) the Fornax galaxy cluster by HESS. We find that those from (i) are among the most stringent constraints currently available, for a large range of DM masses and a variety of decay modes, excluding half-lives up to ~10^26 to few 10^27 seconds.

Astrophysical limitations to the identification of dark matter: indirect neutrino signals vis-a-vis direct detection recoil rates
/ Serpico, Pasquale D. (CERN ; Annecy, LAPTH) ; Bertone, Gianfranco (Paris, Inst. Astrophys. ; Zurich U.)
A convincing identification of dark matter (DM) particles can probably be achieved only through a combined analysis of different detections strategies, which provides an effective way of removing degeneracies in the parameter space of DM models. In practice, however, this program is made complicated by the fact that different strategies depend on different physical quantities, or on the same quantities but in a different way, making the treatment of systematic errors rather tricky.

Diffuse gamma ray constraints on annihilating or decaying Dark Matter after Fermi
/ Cirelli, Marco (CERN ; Saclay, SPhT) ; Panci, Paolo (L'Aquila U. ; Gran Sasso ; Paris U., VI-VII) ; Serpico, Pasquale D (CERN ; Annecy, LAPTH)
We consider the diffuse gamma ray data from FERMI first year observations and compare them to the gamma ray fluxes predicted by Dark Matter annihilation or decay (both from prompt emission and from Inverse Compton Scattering), for different observation regions of the sky and a range of Dark Matter masses, annihilation/decay channels and Dark Matter galactic profiles. We find that the data exclude large regions of the Dark Matter parameter space not constrained otherwise and discuss possible directions for future improvements. [...]
