TL;DR Summary

Scientists at CERN's LHCb have identified a new baryon, Xi-cc-plus, composed of two charm quarks and one down quark. Weighing about four times the mass of a proton, it offers a testbed for quantum chromodynamics and the strong force; discovered after 2023 detector upgrades, it is only the second observed baryon with two heavy quarks and has a lifetime up to six times shorter than a similar earlier baryon.
