To recreate conditions similar to those of the very early universe, powerful accelerators make head-on collisions between massive ions, such as gold or lead nuclei. Learn more about CERN's heavy ion collisions here.
On Friday, 18 November, a test using collisions of lead ions was carried out in the LHC and provided an opportunity for the experiments to validate the new detectors and new data-processing systems ahead of next year’s lead-lead physics run.
The collaboration’s latest study of a “strange”, unstable nucleus known as the hypertriton offers new insight into the particle interactions that may take place at the hearts of neutron stars
Our fifth story in the LHC Physics at Ten series looks at how the LHC has recreated and greatly advanced our knowledge of the state of matter that is believed to have existed shortly after the Big Bang
