A new look at the Y tetraquarks and Ωc baryons in the diquark model
We analyze the hidden charm P -wave tetraquarks in the diquark model, using an effective Hamiltonian incorporating the dominant spin–spin, spin–orbit and tensor interactions. We compare with other P -wave systems such as P -wave charmonia and the newly discovered Ω c baryons, analysed recently in th...

| description | We analyze the hidden charm
P
-wave tetraquarks in the diquark model, using an effective Hamiltonian incorporating the dominant spin–spin, spin–orbit and tensor interactions. We compare with other
P
-wave systems such as
P
-wave charmonia and the newly discovered
Ω
c
baryons, analysed recently in this framework. Given the uncertain experimental situation on the
Y
states, we allow for different spectra and discuss the related parameters in the diquark model. In addition to the presently observed ones, we expect many more states in the supermultiplet of
L
=
1
diquarkonia, whose
J
PC
quantum numbers and masses are worked out, using the parameters from the currently preferred
Y
-states pattern. The existence of these new resonances would be a decisive footprint of the underlying diquark dynamics. |
