Description

Although the existence of the astronomical dark matter is by now well established, its nature is still unresolved. The favoured candidate is a massive and weakly interacting neutral particle, dubbed WIMP, whose relic abundance is compatible with cosmological measurements. If present inside the haloes of galactic systems, these species still annihilate and yield distortions in the various cosmic radiations which a plethora of experiments are searching with increasing accuracy. I will review the status of the current searches. In particular, I will discuss the recently confirmed high-energy positron anomaly as well as the yet unexplained GeV gamma-ray excess from the Galactic center. Antiprotons yield also severe bounds on WIMP properties which may turn out to be crucial. I will finally elaborate on the still remote connections between dark matter indirect searches and the Higgs boson.
