英文摘要	We propose to search for a tetraquark candidate X (ud (s) over bar(s) over bar) in pn -> Lambda Lambda X(ud (s) over bar(s) over bar) -> Lambda Lambda K(+)K(0) or Lambda Lambda KK*. The existence of tetraquark state X (ud (s) over bar(s) over bar) was predicted in the literature due to specific diquark effective degrees of freedom inside hadrons. In order to understand the underlying dynamics for exotic hadrons, a search for the tetraquark X(ud (s) over bar(s) over bar) is strongly recommended. We make an estimate of the production rate of X(ud (s) over bar(s) over bar) in an effective lagrangian theory. The proposed reaction involves two Lambda production, of which the narrow widths make it a great advantage in the analysis of the final state missing mass spectrum.
