Abstract
There may be seven
hadronic molecular states. We construct their corresponding interpolating currents and calculate their masses and decay constants using QCD sum rules. Based on these results, we calculate their relative production rates in
decays using current algebra, that is,
, where
and
are two different states. We also study their decay properties via Fierz rearrangement and further calculate these ratios in the
mass spectrum, that is,
. Our results suggest that the
molecular states of
and
may be observed in future experiments.
