Dark matter is the dominant component of matter in the universe, but to date there is no experimental evidence of its nongravitational interaction with the Standard Model. At particle colliders, dark matter particles may be produced via some unknown intermediate state. So-called Mono-X signatures, in which the presence of invisible particles can be inferred from their recoil against a visible...

DAMIC is a direct detection dark matter experiment using thick silicon CCDs as target and sensor.
This technique is sensitive to nuclear recoil induced by the interaction of low mass WIMP on the target nucleus thanks to the silicon crystal characteristics and low noise readout capabilities.
DAMIC is installed at SNOLAB and has set limits on WIMP-nucleon cross section between 1 and 20...

Recent proposals have suggested that dark energy could arise from interactions related to a new scalar particle. In models where such forces are "screened," existing laboratory constraints on fifth forces and solar system bounds can be avoided. We will present results from table top laboratory searches for new scalars that would be sensitive to certain classes of such screened interactions. ...

Dual phase (liquid - gas) direct detection xenon experiments have recently demonstrated their exceptional capabilities for rare event detection. They examine the interaction of dark matter particles through their scatter off nuclei in the target. This technology currently achieves the most stringent limits on WIMP (Weakly Interacting Massive Particle) searches: it is evolving rapidly since the...

The non-observation of new physics at the LHC and in direct detection experiments puts significant pressure on the idea that dark matter consists of weakly-interacting massive particles (WIMPs) produced from thermal freeze-out. In light of these results I will discuss ways to extend the WIMP idea by introducing new mediators and/or additional states in the dark sector. Doing so affects the...
