Next week, the LHC experiments will start taking data for the LHC's second run. Find out how they used the long shutdown to upgrade their detectors

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
