Abstract
In this study, we choose the scalar and axialvector diquark operators in the color antitriplet as the fundamental building blocks to construct four-quark currents and investigate the diquark-antidiquark type axialvector tetraquark states
in the framework of the QCD sum rules. The predicted tetraquark mass
is in excellent agreement with the experimental value
from the BESIII collaboration, which supports identifying
as the cousin of
with quantum numbers
. We take into account the light flavor
mass-breaking effect to estimate the mass spectrum of the diquark-antidiquark type hidden-charm tetraquark states with strangeness according to previous studies.
