Axial vector tetraquark with S=+2

Abstract

Possibility of an axial vector isoscalar tetraquark with $ud\bar{s}\bar{s}$ is discussed. If the pentaquark ${\Theta }^{+}(1540)$ has the $(qq{)}_{\bar{3}}(qq{)}_{\bar{3}}\bar{q}$ configuration, the isoscalar $ud\bar{s}\bar{s}$(${\vartheta }^{+}$-meson) state with $J^P=1^{+}$ is expected to exist in the mass region lower than or close to the mass of ${\Theta }^{+}(1540)$. Within a flux-tube quark model, a possible resonant state of $ud\bar{s}\bar{s}(J^P=1^{+})$ is suggested to appear around 1.4 GeV with the width $\mathcal{O}(20\sim 50)$ MeV. We propose that the ${\vartheta }^{+}$-meson is a good candidate for the tetraquark search, which would be observed in the $K^{+}{K}^{+}{\pi }^{-}$ decay channel.
