If dark-QCD mediators were produced in pairs in the CMS detector, their signature would be striking.
Interest is growing in new experiments that probe dark-matter candidates such as axions and other very weakly interacting sub-eV particles.
XENON1T is a 3D-imaging liquid-xenon time projection chamber located at Gran Sasso National Laboratory in Italy.
The temporal distribution of solar flares is correlated with the positions of the Earth, Mercury and Venus.
Using three complementary techniques, CMS has now explored a large range in mass, coupling and width.
XENON1T is the first tonne-scale detector of its kind and is designed to search for WIMP dark matter by measuring nuclear recoils from WIMP–nucleus scattering.
The CERN Axion Solar Telescope has reported important new exclusion limits on coupling of axions to photons.
Results show that the density of dark matter in a halo does not gradually fall off with distance, as might be expected, but instead exhibits a sharp edge.
A surprising result at the Max Planck Institute for Extraterrestrial Physics in Germany suggests that dark matter was less influential in the early universe than it is today.
Due for launch in 2020, ESA’s Euclid probe will track galaxies and large areas of sky to find the cause of the cosmic acceleration.
