From Scientific American, Feb. 26, 2016: Evidence for a never-before-seen particle containing four types of quark has shown up in data from the Tevatron collider at Fermilab.
From Gizmodo, Feb. 25, 2016: Physicists from the DZero collaboration have announced the discovery of a new particle, believed to be part of an exotic family called “tetraquarks.”
The Tevatron will shut down at the end of September 2011 after 26 years of colliding particles.
Experiments at the Department of Energy’s Fermilab are close to reaching the critical sensitivity that is necessary to look for the existence of a light Higgs particle.
