Looking back to the day when the Standard Model was completed.
The search for the Standard Model Higgs boson, the missing keystone of the current framework for describing elementary particles and forces, has been going on for some 40 years.
CERN’s director-general, Rolf Heuer, looks beyond the results announced on 4 July to a wider significance.
Studies of heavy-ion collisions at the LHC are challenging and refining ideas on how to probe QCD – the theory of the strong interaction – at high temperature and density.
The new state is observed with a significance exceeding 5σ and a mass of 5945.0 ± 2.8 MeV.
The ATLAS experiment sent the results of more than 40 new analyses to "La Thuille", "Moriond" and other winter conferences.
The ATLAS and CMS collaborations are carrying out a large-scale hunt for hypothetical heavy partners of the Standard Model gauge bosons, the W and the Z.
Researchers in the Modular Neutron Array (MoNA) collaboration have found evidence for a new nuclear-decay mode at the National Superconducting Cyclotron Laboratory (NSCL) at Michigan State University.
The first week of the 47th Rencontres de Moriond, devoted to weak interactions and unified theories, came to a close on 10 March, leaving participants not only impressed but also puzzled by the new r...
