Analysis of the $X_0(2900)$ as the scalar tetraquark state via the QCD sum rules

Abstract

In this article, we study the axialvector-diquark-axialvector-antidiquark ($AA$) type and scalar-diquark-scalar-antidiquark ($SS$) type fully open flavor $cs\bar{u}\bar{d}$ tetraquark states with the spin-parity $J^P=0^{+}$ via the QCD sum rules. The predicted masses $M_{AA}=2.91\pm 0.12\mathrm{GeV}$ and $M_{SS}=3.05\pm 0.10\mathrm{GeV}$ support assigning the $X_0(2900)$ to be the $AA$-type scalar $cs\bar{u}\bar{d}$ tetraquark state.
