The free-electron X-ray laser SwissFEL at the Paul Scherrer Institute (PSI) in Switzerland has hosted its inaugural experiment, marking the facility’s first science result and demonstrating that its...
Read article 'Searches for dark photons at LHCb'
While the dark photon does not couple directly to Standard Model particles, quantum-mechanical mixing between the photon and dark-photon fields can generate a small interaction.
Read article 'ATLAS extends searches for natural supersymmetry'
Not only can SUSY accommodate dark matter and gauge–force unification at high energy, it offers a natural explanation for why the Higgs boson is so light compared to the Planck scale.

No more than a few hundred tZq events and a dozen tttt events were expected after selection.
Read article 'Longitudinal asymmetry tracked in heavy-ion collisions'
In a heavy-ion collision, a longitudinal asymmetry arises due to unequal numbers of participating nucleons from the two colliding nuclei, causing a shift in the centre-of-mass (CM) of the overlapping ...

Read article 'Baby MIND takes first steps'
In mid-October, a neutrino detector that was designed, built and tested at CERN was loaded onto four trucks to begin a month-long journey to Japan. Once safely installed at the J-PARC laboratory in To...
Read article 'Majorana neutrinos remain elusive'
Neutrinoless double beta-decay is only possible if neutrinos and antineutrinos are identical or “Majorana” particles.
