| Summary: | Abstract
We systematically construct all the tetraquark currents/operators of
J
PC
= 1
+-
with the quark configurations
,
, and
(
), and derive their relations through the Fierz rearrangement of the Dirac and color indices. Using the transformations of
and
, we study decay properties of the
as a compact tetraquark state; while using the transformation of
, we study its decay properties as a hadronic molecular state. |
