We consider a characteristic gamma-ray signal coming from Virtual Internal Bremsstrahlung (VIB) of Dark Matter, which is the leading process of photon emission generated by Dark Matter annihilation.
The relation between the gamma-ray excess around 130 GeV and the recent positron excess of AMS-02 is discussed. The gamma-ray excess is explained by VIB of Dark Matter. On the other hand, a...

The nature of dark matter is one of the greatest mysteries of modern cosmology and particle physics. In this talk I will introduce a theory with broken R-parity where the gravitino forms a well-motivated candidate for unstable dark matter. After a brief review of the cosmological motivation for the scenario I will discuss its phenomenology with respect to indirect dark matter searches using...

One of the most important signatures of dark matter in direct detection is
the annual modulation of the signal, due to the motion of the Earth around
the Sun. In inelastic scattering, the minimum velocity a WIMP must have to
deposit a recoil energy at the threshold of the detector is already close
to the galactic escape velocity. In this case the experiment probes the
tails of the dark...

The DRIFT dark matter detector is a 1 cubic meter scale TPC with
direction sensitivity to WIMP recoils operating in the Boulby
Mine in England. The directional sensitivity allows DRIFT to
detect the sidereal modulation of the WIMP recoils and provide
an unambiguous confirmation of a dark matter interaction. We
present recent R&D progress which significantly reduces
our remaining backgrounds.

DAMIC is a novel dark matter experiment that has unique sensitivity to WIMPs with masses below 10 GeV. We summarize the experience gained from previous runs, including a new 5 g detector running at SNOLAB since December 2012. These have demonstrated the outstanding energy response, energy threshold and background characterization of CCD technology, which motivate the construction of a larger...

The Dark Matter Time Projection Chamber (DMTPC) collaboration is
developing prototype detectors to measure the energies and directions of
nuclear recoils. The intended application is to exploit the expected
directional anisotropy of dark matter in the galactic frame to
unambiguously observe dark matter induced recoils. The detectors consist
of low-pressure CF_4 TPC's with CCD cameras,...
