The Crystal Clear collaboration is celebrating its 30th anniversary this April – an opportunity to retrace an unusual journey

The upgraded Muon Forward Tracker, one of ALICE’s main subdetectors, was installed in the cavern in December

The collaboration shows how proton–proton collisions at the Large Hadron Collider can reveal the strong interaction between composite particles called hadrons

The upgraded ALICE Miniframe was reinstalled in the experimental cavern in November

Fabrizio Grosa and Arild Velure are the young laureates of the 2020 award

The refurbished detector was lowered into the ALICE cavern and installed in the experiment in August

The study of light antinuclei – from creation to annihilation – will bolster future indirect dark matter searches

Novel cryostat units have been installed for the High-Luminosity LHC to allow insertion of room-temperature collimators in the LHC’s 1.9 K cryostats

The Large Hadron Collider began its physics programme on this day a decade ago

New vacuum chambers are being developed for the ALICE and CMS experiments

The first measurement, by the ALICE collaboration, of an elliptic-shaped flow for bottomonium particles could help shed light on the early universe
