If dark matter couples feebly enough to evade direct detection, it may still betray itself by stealing energy from a beam. NA64 has put this principle to work for 10 years.
The LHC has entered its third Long Shutdown after a Run 3 that surpassed expectations, beginning four years of upgrades towards the High-Luminosity LHC.
ALPHA has measured the ground-state hyperfine splitting of antihydrogen a hundred times more precisely than before, sharpening its test of CPT symmetry.

Read article 'A hot start for cluster formation'
A bound galaxy protocluster with hot, X-ray-emitting gas has been found just one billion years after the Big Bang.
Read article 'A light on partons at the nuclear edge'
ATLAS has observed that nucleons near the edge of a nucleus have different parton distribution functions from those near its centre.
Read article 'W boson decays to three charged hadrons'
CMS has searched for the rare decay of the W boson into three light charged hadrons, setting the most stringent limit yet on its branching fraction.
Read article 'A new doubly charmed baryon'
LHCb has observed a new doubly charmed baryon, marking the first new particle found with its upgraded detector.
Read article 'Collective flow in hypernuclei'
ALICE has measured the elliptic flow of the hypertriton for the first time, finding that it follows the collective motion of the medium.
Read article 'All entangled around the collider'
Around 100 specialists gathered at CERN to take stock of quantum observables at colliders, a field grown from theoretical curiosity into a body of experimental results.
Read article 'Theorists ponder across scales'
PLANCK 2026 brought more than 250 theorists to CERN to confront puzzles of scale, from the mass of dark matter to the hierarchy between the Higgs and Planck scales.
Read article 'QCD cartographers gather at CERN'
CPOD26 gathered more than 100 researchers at CERN to hunt for the QCD critical point, where the crossover to quark-gluon plasma becomes a first-order transition.
Read article 'Precision loops back to Brookhaven'
LoopFest returned to Brookhaven with the latest in precision quantum field theory, from multi-loop calculations and SMEFT fits to machine learning and quantum information.
Read article 'Two channels for the top–antitop excess'
The CMS collaboration reported an excess of top-antitop pairs in a new decay channel, consistent with the formation of a fleeting quasi-bound state.
Read article 'Final collisions for the RHIC'
On 6 February 2026, beams of oxygen ions circulated through the Relativistic Heavy Ion Collider at Brookhaven National Laboratory for the last time.
Read article 'The kaon stays on script'
Fewer than one in 10 billion charged kaons decay to a pion and a neutrino-antineutrino pair. NA62 has now measured this rate with 40% smaller uncertainty than before.
