LHCb has probed hidden-valley scenarios which exhibit confinement in an analogous way to how the strong nuclear force confines quarks.
The excess could be due to a difficult-to-constrain tritium background, solar axions or solar neutrinos with a Majorana nature, says the collaboration.
The FUNK experiment has set an improved limit on the existence of hidden photons as candidates for dark matter with masses in the eV range.
The collaboration scoured four months of electron-positron collisions at SuperKEKB for evidence of invisibly decaying Z′ bosons.
The CMS collaboration recently used a dedicated set of high-rate “scouting” triggers to extend their search for dark photons to lower energies.
Working at CERN’s Antiproton Decelerator, the international BASE team has set the first laboratory limits on the interaction between antimatter and dark-matter axions
The $3 million prize will be shared equally between 347 researchers who were co-authors of the six papers published by the EHT collaboration on 10 April.
The inferred mass, spin and age of M87* are incompatible with the existence of fuzzy dark matter with masses of the order of a few 10-21 eV.
Cold-atom interferometry could fill a gap in observational capability for gravitational waves in the intermediate-frequency band.
The ATLAS collaboration carried out a first collider search for light scalar particles that could contribute to the accelerating expansion of the universe.
