The LHC had the unique opportunity of colliding xenon nuclei over several hours

The LHC is operating for several hours with the nuclei of xenon atoms

Published in Nature Physics ALICE reports proton collisions sometimes present similar patterns to those observed in the collisions of heavy nuclei

Three decades since the first ultra-relativistic collisions were produced at CERN, the field of heavy-ion physics is still a hot topic

The LHCf experiment begins its annual run to study cosmic rays

For the third time ever the LHC today began colliding beams of protons with lead ions to probe the early universe from which matter emerged

This week’s heavy-ion run at the LHC breaks a symbolic barrier, says CERN accelerator physicist John Jowett

The Large Hadron Collider today collided protons at lower energies than usual to pave the way for studying lead-ion collisions

After some 400 trillion proton-proton collisions delivered to both ATLAS and CMS, the accelerator will now switch to its heavy-ion programme

This week it's the turn of heavy-ion physics to take the spotlight

The ATLAS measurement compared data of 2.76 TeV lead-ion collisions taken in 2011 with proton-proton data from a dedicated run of the LHC in 2013
