On 3 June, experiments at the LHC are set to collect their first physics data in two years, marking the start of the accelerator's second run

The MOEDAL, TOTEM and LHCf experiments are preparing to collect data from collisions in the LHC at 13 teraelectronvolts

CERN researchers answered your questions about the birth of the web, data analysis, and the upcoming LHC physics at 13 TeV

Last night, for the first time, protons collided in the Large Hadron Collider (LHC) at the record-breaking energy of 13 TeV. See the first images

These first collisions at 13 TeV in the LHC are to set up systems that protect detectors from stray particles before they are fully switched on

Watch 11 physicists from the LHC experiments ALICE, ATLAS, CMS and LHCb explain what they hope to discover during the accelerator's second run

This morning, for the first time in two years, proton-proton collisions were delivered to the LHC experiments at injection energy: 450 GeV per beam
