ATLAS gets under the hood of the Higgs mechanism
The detection of longitudinally polarised W boson production at the Large Hadron Collider is an important step towards understanding how the primordial electroweak symmetry broke, giving rise to the masses of elementary particles

CMS finds unexpected excess of top quarks
Data from the CMS experiment at CERN’s Large Hadron Collider reveals an intriguing excess of top-quark pairs, hinting at the first observation of a composite particle with unique properties
-
Symmetry between up and down quarks is more broken than expected
Surprising results from the NA61/SHINE collaboration at CERN show that this so-called isospin asymmetry could point to gaps in physicists’ understanding of how quarks and gluons combine
-
A new piece in the matter–antimatter puzzle
The LHCb experiment at CERN has revealed a fundamental asymmetry in the behaviour of particles called baryons
-
A bestiary of exotic hadrons
The LHC is engaged in a complex quest to understand the exotic offspring of one of the fundamental forces of nature

Observing triplets of weak bosons
ATLAS reports the first observation of a Z boson accompanied by two other carriers of the weak force
