|Abstract: ||If a narrow + pentaquark exists, it is likely that a ud¯s–ud triquark-diquark
configuration is a significant component of its wave function. If so, the mechanism
responsible for the binding of a triquark and a diquark is also likely
to bind the triquark to an ¯s antiquark. We discuss the expected properties
of such a ud¯s–¯s tetraquark meson. In particular, we point out that for a 0+
isoscalar ud¯s¯s meson the lowest allowed decay mode is a four-body KK
channel with a very small phase space and a distinctive experimental signature.|
