摘要：
In this article, we study the axialvector-diquark-axialvector-antidiquark (AA)-type and scalar-diquark-scalar-antidiquark (SS) type fully open flavor csfid tetraquark states with the spin-parity J(P) = 0(+) via the QCD sum rules. The predicted masses M-AA = 2.91 +/- 0.12 GeV and M-SS = 3.05 +/- 0.10 GeV support assigning the X-0(2900) to be the AA-type scalar csud tetraquark state.
