The Riddle of the f0(980) and a0(980): Are They the Quark-Antiquark States?

A. V. Anisovich, V. V. Anisovich, L. G. Dakhno +4

A list of arguments favouring quark-antiquark nature of a0(980) and f0(980) is presented.

Determination of the quarkonium--gluonium content of the isoscalar tensor resonances $f_{2} (1920)$ , $f_{2} (2020)$ , $f_{2} (2240)$ , $f_{2} (2300)$ and of the broad state $f_{2} (2000)$ based on decay couplings to $π^{0} π^{0}, η η, η η^{'}$

V. V. Anisovich, M. A. Matveev, J. Nyiri +1

In the reactions $p p ˉ \to π^{0} π^{0}, η η, η η^{'}$ there are four relatively narrow resonances $f_{2} (1920)$ , $f_{2} (2020)$ , $f_{2} (2240)$ , $f_{2} (2300)$ , and a broad one $f_{2} (2000)$ in the mass r…

Radiative decays of mesons in the quark model: relativistic and non-relativistic approaches

A. V. Anisovich, V. V. Anisovich, V. A. Nikonov

Different conclusions about quark nature of f0(980) based on the analysis of data on the reaction phi(1020) -> gamma f0(980) make it necessary to perform detailed comparison of for…

Quark structure of f0(980) from the radiative decays phi(1020)->gamma f0(980), gamma eta, gamma eta', gamma pi0 and f0(980)->gamma gamma

A. V. Anisovich, V. V. Anisovich, V. A. Nikonov

Partial widths of the radiative decays $ϕ (1020) \to γ f_{0} (980)$ , $γ η$ , $γ η^{'}$ , $γ π^{0}$ and $f_{0} (980) \to γ γ$ are calculated assuming all mesons under consideration to be $q q ˉ$ states:…

The low-mass sigma-meson: Is it an eyewitness of confinement?

V. V. Anisovich, V. A. Nikonov

In the framework of the dispersion relation N/D-method we restore the low-energy pi-pi (IJ^{PC}=00^{++})-wave amplitude sewing it with the previously obtained K-matrix solution for…
