The quest to detect the non-gravitational signals from dark matter particles is now more than 50 years old and is reaching its culmination with the latest generation detectors. In this talk I will review most recent results from the so called indirect searches, which look for dark matter signals in the rich astrophysical data.

We complete the calculation of the wino-nucleon scattering cross section up to the next-to-leading order in α_s. As a result, the uncertainties coming from the perturbative QCD are significantly reduced to be smaller than those from the nucleon matrix elements. The resultant scattering cross section is found to be larger than the leading-order one by about 70%, which is well above the...

Planary Talk

I will give an overview of the present status of dark matter searches at the LHC. I will discuss the validity of the effective field theory approach and the possible search strategies for getting the most out of the next collider run.

We show that the high energy events observed in the IceCube detector - usually interpreted as evidence for an astrophysical neutrino flux - could also be a signal of highly boosted dark matter particles scattering on nucleons. This scenario is for instance realized in models featuring a superheavy DM particle which decays into a much lighter dark sector species. We show that, besides...
