Z(4430)

Z(4430) is a mesonic resonance discovered by the Belle experiment.〔
〕〔
〕 It has a mass of . 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 ,〔 making it a tetraquark candidate. It has the spin-parity quantum numbers JP = 1+.
The particle joins the X(3872), Zc(3900) and Y(4140) as exotic hadron candidates observed by multiple experiments, although it is the first to be confirmed as a resonance.〔(【引用サイトリンク】title=Unambiguous observation of an exotic particle which cannot be classified within the traditional quark model )
