Scientists at CERN’s Large Hadron Collider (LHC) have confirmed the existence of a new class of subatomic particles, exotic hadrons.
A new measurement performed by the LHCb collaboration, one of the four large experiments at the LHC at CERN, has confirmed the existence of the exotic object labeled the Z(4430)-. This particle does not fit into the pattern of particles we have seen up to now. The LHCb result confirms an observation made by the Belle collaboration in 2008 that was later questioned and so resolves this previously unclear situation.
