[ExI] After 48-year search, physicists discover ultra-rare 'triple glueball' particle

[John Grigg]

"Scientists predicted the existence of the particle, known as the odderon,
in 1973, describing it as a rare, short-lived conjointment of three smaller
particles known as gluons. Since then, researchers have suspected that the
odderon might appear when protons slammed together at extreme speeds, but
the precise conditions that would make it spring into existence remained a
mystery. Now, after comparing data from the Large Hadron Collider (LHC),
the 17-mile-long (27 kilometers) ring-shaped atom smasher near Geneva
that's famous for discovering the Higgs boson, and the Tevatron, a
now-defunct 3.9-mile-long (6.3 km) American collider that slammed protons
and their antimatter twins (antiprotons) together in Illinois until 2011,
researchers report conclusive evidence of the odderon's existence."
