A search for double-heavy tetraquark state candidates Xccs¯s¯ decaying to $$D$$$^{+}_{s}$$$$D$$$$^{+}_{s}$$ and $$D$$*$$^{+}_{s}$$$$D$$*$$^{+}_{s}$$ is presented for the first time using the data samples of 102 × 106 Υ(1S) and 158 × 106 Υ(2S) events, and the data samples at √s = 10.52,10.58, and 10.867 GeV corresponding to integrated luminosities of 89.5, 711.0, and 121.4 fb–1, respectively, accumulated with the Belle detector at the KEKB asymmetric energy electron-positron collider. The invariant-mass spectra of the $$D$$$^{+}_{s}$$$$D$$$$^{+}_{s}$$ and $$D$$*$$^{+}_{s}$$$$D$$*$$^{+}_{s}$$ are studied to search for possible resonances.
