At CERN, we probe the fundamental structure of particles that make up everything around us. We do so using the world's largest and most complex scientific instruments.

This week the CMS collaboration is replacing the heart of its detector: its tracking system
The CMS detector’s tracking system, which determines the trajectories of charged particles, is being replaced this week at Point 5
The ATLAS PhD Grant gives students an opportunity to benefit from world-class research, supervision and training within the ATLAS collaboration
ATLAS measurements show proton has more strange quarks than previously thought
On the experiments’ side, the extended year-end technical stop is a precious opportunity to carry out repairs and maintenance works on their detectors
The LHCb collaboration has presented a new measurement of a rare particle decay, providing another strong confirmation of the Standard Model
The LHC experiment collaborations presented their latest results at the Quark Matter conference on how matter behaved in the universe's first moments
CERN’s LHCb experiment has found evidence of a symmetry violation that could contribute to solve the mystery of the missing antimatter
The ALPHA collaboration celebrate this week after twenty years of work resulted in them seeing, for the first time, antimatter's light spectrum
In a Nature paper, the ALPHA collaboration reports the first ever measurement on the optical spectrum of an antimatter
On 18 December 2016 the Sun aligned with the black hole in the centre of the Milky Way, allowing CAST to search for any exotic particles it might emit
ATLAS reports the first measurement of the W boson mass using LHC proton–proton collision data at 7 TeV
