Dark Matter

BASE develops a new technique to detect ultralight dark matter.

In a recent work published in Physical Review Letters [1], the Baryon Antibaryon Symmetry Experiment (BASE) at CERN has placed new limits on a possible coupling between photons and hypothetical axionlike dark matter particles with masses between 2.…

BabyIAXO submits for publication its Conceptual Design Report

The International Axion Observatory (IAXO) will search for axions or axion-like particles emitted by the Sun with unprecedented sensitivity. Axions are hypothetical particles that appear in extensions of the Standard Model that include the Peccei-…

BASE probes antimatter - dark matter interaction

In a recent paper, the BASE collaboration presented results from a direct search for interactions of antimatter with dark matter and placed direct constraints on the interaction of ultralight axion-like particles (dark-matter candidates) with…

Experimental searches for solar and dark matter axions

Detection of solar axions If axions exist, they would be produced in large quantities in the solar interior. Photons from the solar plasma would convert into axions in the Coulomb fields of charged particles via the Primakoff axion-photon conversion…

XENON1T probes deeper into Dark Matter WIMPs

Results from XENON1T, the world’s largest and most sensitive detector dedicated to a direct search for Dark Matter in the form of Weakly Interacting Massive Particles (WIMPs), were reported on the 28th May, by the spokesperson, Prof. Elena Aprile of…

Search for axions in streaming dark matter

    Streaming dark matter (DM) axions may be the better source for their discovery than the widely assumed isotropic DM. Because, a large axion flux enhancement can take place, temporally, due to gravitational lensing when the Sun and/or a planet…
