Abstract
Motivated by the analogous properties of
and
, we tentatively assign
as the
-type hidden-charm tetraquark state with
, where A denotes the axialvector diquark states, and explore
-type tetraquark states without strange, with strange, and with hidden-strange via QCD sum rules in a consistent manner. We then explore the hadronic coupling constants in the two-body strong decays of tetraquark states without and with strange via QCD sum rules based on rigorous quark-hadron duality and acquire partial and total decay widths. The present calculations support assigning
as the
-type tetraquark state with
, while the predictions for its strange cousin
state can be confronted with experimental data in the future.
