The LHCb collaboration has spotted a new particle. Its mass and other properties place it squarely in the charmonium family that includes the better-known J/ψ particle, which was the first particle containing a “charm quark” to be discovered and won its discoverers a Nobel prize in physics. Future studies of the properties of this new charmonium state and its relatives will help physicists better understand the strong force that binds together quarks, among the smallest particles that we know of.
