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

On 8 May 2025, CERN Director-General Fabiola Gianotti and Irish Minister for Further and Higher Education, Research, Innovation and Science James Lawless signed an agreement admitting Ireland as an Associate Member State of CERN

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

Substantial contributions to the 2026 update of the European Strategy for Particle Physics set the stage for discussions that will define the next flagship collider at CERN

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

The Breakthrough Prize in Fundamental Physics was awarded to the ALICE, ATLAS, CMS and LHCb collaborations during a ceremony held in Los Angeles on 5 April

Released today, a report of a study investigating the project’s feasibility will serve as input for the European Strategy for Particle Physics and be assessed by the CERN Council in the coming months

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

The LHCb experiment at CERN has revealed a fundamental asymmetry in the behaviour of particles called baryons

The LHC is engaged in a complex quest to understand the exotic offspring of one of the fundamental forces of nature
