Theorists at the University of Pittsburgh and Swansea University have shown that recent experimental results from the CERN collider give strong evidence for a new form of matter. The experiment at CERN examined a heavy particle called a Lambda b that decays to lighter particles, including the familiar proton and the famed J/psi, discovered in 1974. The researchers say the data can be understood only if a new type of matter exists. The explanation requires the existence of several new particles that consist of four quarks and one antiquark, called “pentaquarks”Read Long Article
