A New Look at the $Y$ Tetraquarks and ${\Omega }_c$ Baryons in the Diquark Model

Ahmed Ali, Luciano Maiani, Anatoly V. Borisov +5

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 c…
