The invariant-mass spectra of the Ds+Ds+ and Ds∗+Ds∗+ 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)→Xccs¯s¯+anything)×B(Xccs¯s¯→Ds+Ds+(Ds∗+Ds∗+))] in ϒ(1S,2S) inclusive decays and the product values of Born cross section and branching fraction [σ(e+e-→Xccs¯s¯+anything)×B(Xccs¯s¯→Ds+Ds+(Ds∗+Ds∗+))] in e+e- collisions at s=10.52, 10.58, and 10.867 GeV under different assumptions of Xccs¯s¯ masses and widths are obtained.12 page(s)application/pdfenIn CopyrightArticle - Refereedhttps://doi.org/10.1103/PhysRevD.105.0320021053Piilonen, Leo [0000-0001-6836-0748]2470-0029
