Abstract
In this study, we tentatively identify
as the
molecular state and distinguish the isospins of current operators to explore in detail the
,
,
,
,
,
,
, and
molecular states without strange, with strange, and with double strange in the framework of QCD sum rules. The present exploration favors identifying
(
) as the
(
) molecular state with the spin-parity
(
) and isospin
, and the observation of their cousins with the isospin
in the
invariant mass distributions would decipher their inner structures.
