摘要	We study the masses of open charm and bottom tetraquark states within the diquark-antidiquark scenario in the relativized quark model proposed by Godfrey and Isgur. The diquark and antidiquark masses are first solved by relativized quark potential, and then treated as the usual antiquark and quark, respectively. The masses of tetraquark states are obtained by solving the Schrodinger-type equation between the new diquark and antidiquark. We find the masses of sq (b) over bar(q) over bar tetraquark configuration are much higher than that of X(5568). This conclusion disfavors the possibility of X(5568)as a tetraquark state within the diquarkantidiquark scenario. Further experimental searches are needed to clarify the nature of the signal observed by the D0 Collaboration.
