Abstract
We study the mass spectra of D-wave excited
tetraquark states with
and
in both symmetric
and antisymmetric
color configurations using the QCD sum rule method. We construct the D-wave diquark-antidiquark type of
tetraquark interpolating currents in various excitation structures with
. Our results support the interpretation of the recently observed
resonance as a D-wave
tetraquark state with
in the
or
excitation mode, although some other possible excitation structures cannot be excluded exhaustively within theoretical errors. Moreover, our results provide the mass relations
and
for the positive and negative
-parity D-wave
tetraquarks, respectively. We suggest searching for these possible D-wave
tetraquarks in both the hidden-charm channels
and
, as well as open-charm channels such as
and
.
