The collaboration has observed a new kind of “pentaquark” and the first-ever pair of “tetraquarks”

Physicists seek to replace harmful chlorofluorocarbons with novel “eco-gases”

The two barrels of the largest pixel detector ever built have been successfully lowered into the cavern and stand ready for commissioning

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

In new results, ATLAS physicists describe novel techniques used to accurately align the muon spectrometer

The CERN Quantum Technology Initiative will explore the potential of devices harnessing perplexing quantum phenomena such as entanglement to enrich and expand its challenging research programme

CMS now has a new layer of detectors: 144 gas electron multiplier (GEM) chambers have been installed to detect the muons produced in the very forward region of CMS

The ATLAS Inner Detector can measure the position of charged particles that pass through it to better than a 100th of a millimetre! To reach that precision, the detector must be aligned to equal or better accuracy

The assembly of the new muon small wheels and the upgrades on the electronics and trigger systems are progressing well
