Curiouser and curiouser: a riddle at the ALICE detector

In 2023, the ALICE experiment was ready for their best year yet, until a mysterious signal threatened everything. As the LHC wraps up its 2025 lead-ion run, physicists recall how they worked together to solve the puzzle.

Dark Matter: A Worldwide Search

Something is out there. As far as scientists know, just 15% of the matter in the universe is the ordinary kind we can see. The other 85%, called dark matter, remains beyond detection, invisibly affecting the movements of galaxies and subtly warping our view of the stars.

A tasty celebration of the tau neutrino

On July 21, 2000, the DONUT collaboration at Fermilab announced the detection of tau neutrinos for the first time. Here are a few ideas for celebrating 25 years of the most elusive of elusive particles.

Elusive romance of top-quark pairs observed at the LHC

The CMS and ATLAS experiments at CERN’s Large Hadron Collider have observed an unforeseen feature in the behaviour of top quarks that suggests that these heaviest of all elementary particles form a fleeting union.
