“…The authors of Ref. [473] calculated the mass-spectra of the state [bb][ bb ] in a non-relativistic framework that includes the Cornell-like potential along with the relativistic correction term to the potential and spin-dependent interaction. They found that the masses of Sand P-wave states are between 18.7 and 19.4 GeV, in which the masses of S-wave states are less than the η b (1S)η b (1S), η b (1S)Υ(1S), and Υ(1S)Υ(1S) thresholds.…”

According to the classification of the quark model, the hadrons going beyond three-quark baryon and quark-antiquark meson pictures are called exotic hadrons. Many new hadrons have been observed since 2003, some of which exhibit exotic behaviors. There are a lot of excellent review articles on exotic hadrons available so far; the present article tries to focus on the recent experimental and theoretical progress on the exotic states from the perspective of the quark model. Although lattice quantum chromodynamics may give the final answer of the problem, the phenomenological models are still powerful tools to explore the exotic states and to provide insight on the phenomenology of hadrons. The spatial and color structures of multiquark states and the channel coupling calculation are emphasized through reviewing some bound states, molecular and color structure resonances. Finally, the unquench effects of some exotic states are reviewed. With the accumulation of experimental data on multiquark states and inspiration of underlying theory developments, more reasonable phenomenological models incorporating multi-body interactions and high Fock components to unify the description of normal hadrons and exotic hadrons are expectable.

“…The present work aims at studying the mass spectra of all charm tetraquarks in the configuration of sextet-antisextet. In our earlier research, we investigated tetraquarks in antitriplet-triplet configuration [9][10][11][12][13][14][15]. The mass spectra of the tetraquark are determined in this study by applying a Cornell-like potential with a first-order correction in mass.…”

For the diquark-antidiquark system, a non-relativistic model with relativistic corrections is applied in the sextet-antisextet configuration to determine the mass spectra of all charm tetraquarks. Using Cornell-like potential, the Schrödinger equation for the Charmonium meson is numerically solved to get the fitting parameters. The current study uses parameters derived from charmonium spectra to predict the mass spectra of all charm tetraquarks in sextet-antisextet configuration, reducing a four-body problem to a two-body problem. The potential decay channels are described using the framework of the quarkonium-like annihilation process.
