True or False: heavy-ion edition 💫 This year’s #HeavyIon run has just started at the Large Hadron Collider, but how much do you know about it? Listen to Marco Van Leeuwen, spokesperson of the @ALICEexperiment, as he confirms or corrects some of your ideas about the heavy-ion run, the quark-gluon plasma, and heavy-ions. Do you have any questions about the heavy-ion run at the #LHC? Leave them in the comments below and we’ll answer in the next videos. Stay tuned for more! Find out more: home.cern/news/news/experime…

So it begins… the heavy-ion run at the #LHC 💪 Yesterday at 11.13 am, a new #HeavyIon run began at the Large Hadron Collider, smashing together lead ions at an energy of 5.36 TeV per nucleon pair. While the LHC mostly collides protons, once a year it collides heavy ions – such as lead nuclei – a key ingredient for preparing the primordial soup called the quark–gluon plasma, a state of matter known to have existed shortly after the #BigBang. For the next 17 days, every minute counts to take lead–lead collision data. Find out more: home.cern/news/news/experime…
