Pentaquark implications for exotic mesons

Abstract

If the exotic baryon ${\Theta }^{+}(1540)$ is a correlated $udud\bar{s}$ with $J^P={1/2}^{+}$, then there should exist an exotic meson, $J^P=1^{-}$ ${\vartheta }^{+}(S=+2)$ $\to K^{+}{K}^0$ $\sim 1.6$GeV with width $O(10-100)$MeV. The ${\pi }_1(1400;1600)$ may be broad members of {\bf 10} $\pm$ \10bar in such a picture. Vector mesons in the 1.4 - 1.7GeV mass range are also compared with this picture.
