Spectroscopy of hidden-charm tetraquarks in diquark model
A nonrelativistic model is used to study hidden-charm tetraquarks within a diquark–antidiquark configuration. Using the perturbation theory, we estimate the masses of the heavy tetraquarks with hidden charm. Our present analysis suggests the charmonium-like states: X (3860), X (3872), Z c ( 3943 ) ,...

| Zusammenfassung: | A nonrelativistic model is used to study hidden-charm tetraquarks within a diquark–antidiquark configuration. Using the perturbation theory, we estimate the masses of the heavy tetraquarks with hidden charm. Our present analysis suggests the charmonium-like states:
X
(3860),
X
(3872),
Z
c
(
3943
)
,
X
(4140),
Z
c
(
4430
)
and
X
(4700) can be accommodated in tetraquark picture. We particularly find that the
Z
c
(
4430
)
may be treated as the first radial excitation of
X
(3872). |
