The European Organization for Nuclear Research (CERN) has shed light on the structure of "exotic" particles. +Get the most important news from Switzerland in your inbox These particles have four quarks, whereas protons and neutrons, for example, only have three. For a long time, the existence of these exotic particles was only theoretical. It is only recently that physicists have accumulated evidence of their reality. However, the true nature of their structure remained a mystery. Research carried out at CERN is now revealing more. + Switzerland risks exclusion from European 'CERN for AI' Scientists at CERN have analysed the traces left by proton collisions produced by the Large Hadron Collider (LHC), the world's most powerful particle accelerator. The data was collected between 2016 and 2018. According to an article published in the journal Nature, the physicists examined the structure of exotic particles composed of two "charm" quarks and two "charm" antiquarks. The physicists ...
