Abstract
Abstract
We study
and
states as mixed states in QCD sum rules. By calculating the two-point correlation functions of pure states of their corresponding currents, we review the mass and coupling constant predictions of
,
, and
states. By calculating the two-point mixed correlation functions of
and
currents, we estimate the mass and coupling constants of the corresponding "physical state" that couples to both
and
currents. Our results suggest that for
states, the
and
components are more likely to mix, while for
and
states, there is less mixing between
and
. Our results suggest the Y series of states have more complicated components.
