Physicists on CERN's LHCb collaboration say they've observed three new exotic particles - X(4274), X(4500) and X(4700) - and also confirmed the existence of a fourth one, X(4140).
Hints of an unexpected new particle could be confirmed within day. And if it is, the Standard Model could be going down
In December, the ATLAS and CMS experiments reported what could be the first hint of a new massive particle that spits out two photons as it decays. Now, physicists are presenting their latest analyses, including a full investigation of this mysterious bump. Both experiments have come to the same conclusion -- the bump is still there.
Physicists working at the Large Hadron Collider reported an unusual bump in their signal. But this time, they have no idea where the bump came from.
CERN researchers have observed a new particle --- the Chi-b(3P) --- in the ATLAS experiment at the Large Hadron Collider, University of Birmingham and
