Z(4430) is a mesonic resonance discovered by the Belle experiment. It has a mass of 4430 MeV/ c. The resonant nature of the peak has been confirmed by the LHCb experiment with a significance of at least 13.9 σ. The particle is charged and is thought to have a quark content of c c d u, making it a tetraquark candidate. It has the spin-parity quantum numbers J = 1.
