New measurement of the mass of the Z boson showcases the Large Hadron Collider’s growing role in precision physics

New data from the ALICE experiment, collected when no particle beams were circulating in the LHC during pauses in Run 2, may contribute to solving a puzzle surrounding cosmic muons

The organisers of the early-career researchers’ white paper for the European Strategy for Particle Physics coordinated a collective effort that provided input for the Strategy update

The CMS collaboration presents a new search for the decay of a Higgs boson into charm quarks, bringing physicists closer to unravelling how this unique particle endows matter with mass

Near-miss collisions between high-energy lead nuclei at the LHC generate intense electromagnetic fields that can knock out protons and transform lead into fleeting quantities of gold nuclei

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

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

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
