The LHC’s proton run came to an end on Wednesday 24 October with an excellent result of 160 fb-1 of data accumulated since the start of 2015

Precision results from the TOTEM experiment provide further explanation on proton-proton interactions at high energies

Exploiting CERN’s know-how in trapping single particles, a team in Heidelberg has found that the proton is lighter than we thought

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

The switch - a test for a longer proton-lead run scheduled for January to February 2013 - presented numerous technical challenges
