摘要：

We analyze various possible interpretations of the narrow state D-sJ(2632) which lies 100 MeV above threshold. This interesting state decays mainly into D(s)eta instead of (DK+)-K-0. If this relative branching ratio is further confirmed by other experimental groups, we point out that the identification of D-sJ(2632) either as a c (s) over bar state or more generally as a (3) over bar state in the SU(3)(F) representation is probably problematic. Instead, such an anomalous decay pattern strongly indicates D-sJ(2632) is a four-quark state in the SU(3)(F) 15 representation with the quark content 1/2root2 (ds (d) over bar +sd (d) over bar +su (u) over bar -2ss (s) over bar)(c) over bar. We discuss its partners in the same multiplet and the similar four-quark states composed of a bottom quark B-sJ(0)(5832). Experimental searches of other members especially those exotic ones are strongly called for.
