Description
The possibility of an axial-vector isoscalar tetraquark with udss is discussed. If the pentaquark Θ+(1540) has the (qq)3(qq)3q configuration, the isoscalar udss (θ+-meson) state with JP=1+ is expected to exist in the mass region lower than, or close to, the mass of Θ+(1540). Within a flux-tube quark model, a possible resonant state of udss(JP=1+) is suggested to appear around 1.4 GeV with the width O(20∼80) MeV. We propose that the θ+-meson is a good candidate for the tetraquark search, which would be observed in the K+K+π- decay channel
