A new particle has been discovered by the Large Hadron Collider, as CERN physicists are now dubbing this particle as one that is "doubly charmed" due to its composition. Why is this the case, and what's the deal with this description?
According to a report from the New York Times, the new particle has been given the codename Xi-cc++, and the fact that it has two charm quarks (hence the "twice the charm" and "doubly charming" sobriquets given by news publications) could help scientists delve deeper into how quarks intermingle with each other. Quarks, as the Times noted, are the tiny particles that serve as building blocks of both protons and neutrons, which, in turn, make up most of ordinary matter as we know it.
Further explaining the new discovery from the Large Hadron Collider at the CERN physics lab outside Geneva, Switzerland, the New York Times wrote that protons and neutrons are made up of up quarks and down quarks. Protons are composed of two up quarks and one down quark, while neutrons have the opposite — one up quark and two down quarks. Either way, quarks come in triplets in this case, and these groups are also called baryons.
