The Spherical Proportional Detector is a new type of radiation detector based on a spherical geometry. It consists of a large spherical gas volume with a central electrode forming a radial electric field. A small spherical sensor located at the center is acting as a proportional amplification structure.
Combination of sub-keV energy threshold and versatility of the target (Ne, He, H) opens...

A variety of experiments have been developed over the past decades, aiming at the detection of Weakly Interactive Massive Particles (WIMPs) via their scattering in an instrumented medium. The sensitivity of these experiments has improved with a tremendous speed, thanks to a constant development of detectors and analysis methods. Detectors capable of reconstructing the direction of...

Searching for cosmic-origin rare new physics signals at Earth-surface-based detectors is usually challenging because of huge cosmic backgrounds.
In order to avoid such a challenge, underground experiments are thus strongly motivated.
If a signal of interest involves many features, however it becomes possible to isolate signal events from background ones.
Along this line, I discuss boosted...

We consider a model of decaying dark matter whose lifetime is comparable to the age of the universe. Its late decay to slightly lighter dark matter particle plus "non-interacting" particle can solve small scale problems. We will also show a smoking-gun signature of "non-interacting" particles from the dark matter decay.
