The CERN Council decided to update the European Strategy for Particle Physics
Today, following more than two years of intense work of the European particle physics community under the auspices of the European Strategy Group, the CERN Council updated the European Strategy for Particle Physics [link to Resolution], which sets out an ambitious scientific vision for the field. The 2026 Strategy update offers a clear path to

ATLAS observes new composite particle
Physicists from the ATLAS Collaboration reported the first observation of a new particle.

ATLAS sets record limits on Higgs boson’s self-interaction
The result is based on over 300 inverse femtobarns of proton–proton collision data, which is equivalent to 30 000 trillion collisions

ATLAS acts as a cosmic-ray laboratory
The ATLAS Collaboration reports its first measurement of proton–oxygen collisions at the LHC, which recreate cosmic-ray interactions with Earth’s atmosphere

CMS looks deep inside quarks
The CMS Collaboration has probed deep inside quarks to search for potential building blocks within them

Mark Rayner (1983 – 2026)
Mark Rayner(1983 – 2026) — It was with profound shock and sadness that we learned of the sudden passing of staff member Mark Rayner, Editor of CERN Courier magazine, on 23 March. Mark was born in Hounslow, England, on 7 October 1983 and studied physics at Worcester College, University of Oxford, from 2002 to 2006.

CMS strengthens the case for toponium
A new independent measurement by the CMS experiment at the LHC is consistent with the existence of the most massive composite particle ever observed, the momentary union of a top quark and its antiquark

ALICE sees new sign of primordial plasma in proton collisions
The ALICE Collaboration takes a step further in addressing the question of whether a quark–gluon plasma can be formed in proton–proton and proton–nucleus collisions

ATLAS sets strong limits on supersymmetry
Using machine-learning techniques, the ATLAS Collaboration has searched deep for signs of particles that could help answer some of the greatest mysteries of physics

LHCb Collaboration discovers new proton-like particle
Composed of two charm quarks and one down quark, the doubly charmed particle is four times heavier than a proton
