Abstract The scalar resonances $$X(3915), X(3960), X_0(4140)$$ X ( 3915 ) , X ( 3960 ) , X 0 ( 4140 ) are considered as exotic four-quark states: $$cq\bar{c} \bar{q}, cs\bar{c} \bar{s}, cs\bar{c}\bar{s}$$ c q c ¯ q ¯ , c s c ¯ s ¯ , c s c ¯ s ¯

Radial and orbital Regge trajectories in heavy quarkonia

Autor: Bakker, A. M. Badalian B. L. G.

Publikováno v: Phys. Rev. D 100, 054036 (2019)

The spectra of heavy quarkonia are studied in two approaches: with the use of the Afonin-Pusenkov representation of the Regge trajectory for the squared excitation energy $E^2(nl)$ (ERT), and using the relativistic Hamiltonian with the universal inte

The formalism of the coupled $q\bar q$ and the $\varphi\varphi ( \pi-\pi$, $K\bar K, \pi K,...$) scalar channels is formulated, taking into account the ground and radial excited $q\bar q$ poles. The basic role is shown to be played by the transition

The dynamical picture of a quark-antiquark interaction in light mesons, which provides linearity of radial and orbital Regge trajectories (RT), is studied with the use of the relativistic string Hamiltonian with flattened confining potential and taki

We study the universal static potential V st(r) and the force, which are fully determined by two fundamental parameters: the string tension σ = 0.18 ± 0.02 GeV2 and the QCD constants $$\Lambda _{\overline {MS} } (n_f )$$ , taken from pQCD, while th
