Abstract: A search for double-heavy tetraquark state candidates Xcc¯s¯s decaying to D+sD+s and D*+sD*+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+sD+s and D*+sD*+s are studied to search for possible resonances. No significant signals are observed, and the 90% confidence level upper limits on the product branching fractions [B(Υ(1S,2S)→Xcc¯s¯s+anything)×B(Xcc¯s¯s→D+sD+s(D*+sD*+s))] in Υ(1S,2S) inclusive decays and the product values of Born cross section and branching fraction [σ(e+e−→Xcc¯s¯s+anything)×B(Xcc¯s¯s→D+sD+s(D*+sD*+s))] in e+e− collisions at √s=10.52, 10.58, and 10.867 GeV under different assumptions of Xcc¯s¯s masses and widths are obtained.
