| Zusammenfassung: | Motivated by the large branching fractions of
and the light exotic candidates, we found that there may exist molecular states composed of
and
, which correspond to
and
observed a few decades ago. The branching fractions of
and
to various
and
channels were estimated in the molecular scenario. In addition, the large branching fractions of
indicate sizable molecular components in the
state. Thus, we consider
as the superposition of the
,
, and
molecular states. These molecular components have a significant impact on the light hadron decays of
, which may elucidate the long standing
puzzle. |
