Analysis of the X0(2900) as the scalar tetraquark state via the QCD sum rules
Zhi-Gang Wang
Abstract
In this article, we study the axialvector-diquark–axialvector-antidiquark (AA)-type and scalar-diquark–scalar-antidiquark (SS) type fully open flavor [Formula: see text] tetraquark states with the spin-parity [Formula: see text] via the QCD sum rules. The predicted masses [Formula: see text] GeV and [Formula: see text] GeV support assigning the [Formula: see text] to be the AA-type scalar [Formula: see text] tetraquark state.
