Abstract
In the framework of the improved chromomagnetic interaction model, we complete a systematic study of the S-wave tetraquark states
(
, and
) with different quantum numbers:
,
, and
. The mass spectra of tetraquark states are predicted, and the possible decay channels are analyzed by considering both the angular momentum and
-parity conservation. The recently observed hidden-charm tetraquark states with strangeness, such as
,
, and
, can be well explained in our model. Additionally, according to the wave function of each tetraquark state, we find that the low-lying states of each
configuration have a large overlap to the
and
meson basis, instead of the
and
meson basis. This indicates that one can search these tetraquark states in future experiments via the channel of
and
mesons.
