The LHC is preparing to restart at almost double the collision energy of its previous run. The new energy will allow physicists to check previously untestable theories, and explore new frontiers in particle physics. When the LHC is on, counter-rotating beams of particles will be made to collide at four interaction points 100 metres underground, around which sit the huge detectors ALICE, ATLAS, CMS and LHCb. In the video above, engineers and technicians prepare these four detectors to receive the

Lead-lead collisions start at the LHC after 5 years This week the heavy-ion physics season started for the Large Hadron Collider experiments, at the record energy of 6.8 TeV for the first time ever. The ongoing heavy-ion run is expected to bring significant advances in our understanding of quark-gluon plasma, the state of matter believed to have filled the #Universe up to a millionth of a second after the #BigBang. Take a look at the behind-the-scenes in the different control rooms and how physi

The first pieces of LHCb Experiment at CERN’s new scintillating-fibre particle-tracking detector, or SciFi, have just journeyed 100 metres down to be installed in the experiment’s underground cavern. Find out more: https://home.cern/news/news/experiments/scifi-moment-lhcb-experiment | CERN

The beauty in LHCb 😁 The LHCb Experiment at CERN specialises in investigating the slight differences between matter and #antimatter by studying a particle called the "beauty quark" or the "b quark". Learn from LHCb Experiment physicists Yasmine, Elena and Sascha how the experiment plans to make the best of chapter three of #LHCRun3. Do you know what the b stands for in the experiment’s name?
