Particle Physics Advances CERN’s LHCb experiment confirmed the doubly charmed baryon Ξcc⁺ on March 17, featuring two charm quarks and one down quark with high significance. This resolves prior discrepancies and advances quark-gluon plasma studies. Quantum & Materials Researchers discovered a new quantum state in semimetal CeRu₄Sn₆, bridging quantum criticality and topology. Physicists also created…
